Fill in the Blanks

Question. The smallest positive number that is a factor of every counting integer is _____.
Answer: 1
Explanation: You can divide any whole number by 1 without leaving any remainder, which makes 1 a factor of every number!

Question. A prime number like 37 has exactly _____ factors.
Answer: 2 (1 and 37)
Explanation: Prime numbers cannot be split into equal rows or tables other than 1 single line: 1 × 37 = 37.

Question. The first common multiple of 5 and 8 is _____.
Answer: 40
Explanation: If you count by 5s (5, 10, 15... 40) and by 8s (8, 16, 24, 32, 40), 40 is the very first number that appears in both lists.

Question. On a cobbled trail, Robby the rabbit takes leaps of 4 steps; starting from 0, he lands precisely on the food at tile number _____.
Answer: 64
Explanation: Robby jumps on multiples of 4. Since 4 × 16 = 64, he lands right on tile 64 to eat his carrot!

Question. The only shared factor between any two consecutive numbers is _____.
Answer: 1
Explanation: Numbers that sit side-by-side on the number line (like 12 and 13) never share any common factor bigger than 1.

Question. Sher Khan goes hunting every 3rd day and Bagheera every 5th day; the initial day they will hunt together is the _____ day.
Answer: 15th
Explanation: They meet on days that are multiples of both 3 and 5. The smallest common multiple is 3 × 5 = 15.

Question. The common divisors of 12 and 16 are 1, 2, and _____.
Answer: 4
Explanation: Factors of 12 are 1, 2, 3, 4, 6, 12 and factors of 16 are 1, 2, 4, 8, 16. The numbers in both lists are 1, 2, and 4.

Question. If Mowgli jumps in strides of 10 steps starting at 0, the first three numbered stones he lands on are 10, 20, and _____.
Answer: 30
Explanation: Jumping by 10 means skip counting by tens: 0 + 10 = 10, then 20, then 30.

True or False

Question. Factors of even numbers must always be even numbers.
Answer: False
Explanation: Even numbers have odd factors too! For example, the factors of 6 are 1, 2, 3, and 6 (where 1 and 3 are odd).

Question. Factors of odd numbers cannot be even.
Answer: True
Explanation: An odd number can never be divided evenly by an even number (like 2, 4, or 6), so its factors are always odd.

Question. Multiples of odd numbers can never be even numbers.
Answer: False
Explanation: When you multiply an odd number by an even number, the answer is even! For example, 3 × 2 = 6, which is an even number.

Question. The number zero can serve as a factor of any counting number.
Answer: False
Explanation: You can never divide by zero, so 0 cannot be a factor of any number.

Question. One of the common multiples of two consecutive numbers is their product.
Answer: True
Explanation: For neighbor numbers like 3 and 4, their product (3 × 4 = 12) is always a multiple of both 3 and 4.

Question. Deeku the deer leaps 6 steps at a time and can reach tile 64 without jumping over it.
Answer: False
Explanation: Deeku lands on 60 (6 × 10) and then jumps straight to 66 (6 × 11), hopping right over tile 64!

Questions / Short Question Answers

Question. Food is placed at tile 64 of a cobbled path. Robby the rabbit jumps 4 steps each time, while Deeku the deer jumps 6 steps each time. Will both animals reach the food?
Answer: No, only Robby will reach the food.
Explanation: 64 is a multiple of 4 (4 × 16 = 64), so Robby lands right on it. But 64 is not a multiple of 6 (6 × 10 = 60 and 6 × 11 = 66), so Deeku skips past it.

Question. Sher Khan hunts every 3rd day, and Bagheera hunts every 5th day. If both begin on day 0, list three days when they hunt together.
Answer: 15th day, 30th day, and 45th day
Explanation: They meet on days that are common multiples of 3 and 5 (15, 30, 45, 60...).

Question. Mowgli wishes to visit his friend Baloo the bear at stone 30, but must avoid Sher Khan's house at stone 25. What jump lengths can Mowgli choose?
Answer: Jump sizes of 2, 3, 6, 10, 15, or 30 steps
Explanation: Mowgli must pick factors of 30 that are NOT factors of 25. Factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30. Removing 1 and 5 (which land on 25) leaves 2, 3, 6, 10, 15, and 30.

Question. What are the common factors of the numbers 24 and 36?
Answer: 1, 2, 3, 4, 6, and 12
Explanation: Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24. Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36. The numbers appearing in both lists are 1, 2, 3, 4, 6, and 12.

Question. Mowgli needs to choose a step size that lands on both Kaa the snake at 21 and Akela the wolf at 35. What jump sizes could he select?
Answer: 1 step or 7 steps
Explanation: Find the common factors of 21 (1, 3, 7, 21) and 35 (1, 5, 7, 35). Only 1 and 7 divide both numbers evenly.

Question. Why is 13 called a prime number?
Answer: Because it has only two factors: 1 and 13.
Explanation: A prime number cannot be made by multiplying any other smaller counting numbers together—only 1 × 13.

Question. Which numbers among 10, 16, 27, 36, and 48 can be reached by jumps of 4 steps from 0?
Answer: 16, 36, and 48
Explanation: Test for divisibility by 4: 16 = 4 × 4, 36 = 4 × 9, and 48 = 4 × 12. 10 and 27 leave remainders.

Question. What are all the factors of 20 that can be shown using rectangle arrays?
Answer: 1, 2, 4, 5, 10, and 20
Explanation: You can arrange 20 dots into arrays of 1 × 20, 2 × 10, and 4 × 5. These give all the factors of 20.

Question. From the list 22, 25, 30, 40, 55, 62, 75, 90, which numbers are divisible by 2, 5, and 10 all together?
Answer: 30, 40, and 90
Explanation: Any number ending in 0 is divisible by 10, and every number divisible by 10 is also automatically divisible by both 2 and 5!

Question. Can Mowgli meet his friend the spider sitting at 9 by taking jumps of 2 steps from 0?
Answer: No, he cannot meet the spider.
Explanation: Jumping by 2 lands only on even numbers (0, 2, 4, 6, 8, 10). Since 9 is an odd number, Mowgli hops right past it.

Match the Following

Question. Match each number pair in Column A with their first three common multiples in Column B:

Explanation: A common multiple is a number that appears in the multiplication tables of both numbers. The smallest one is the Lowest Common Multiple (LCM).

Question. Sort the following collection of numbers based on their divisibility rules:

Explanation: Even numbers end in 0, 2, 4, 6, or 8. Multiples of 5 end in 0 or 5. Numbers ending in 0 belong to both groups and are divisible by 10 as well!

Vocabulary Activity - "Guess the Word"

Question. Guess the Word: I am a whole number that divides evenly into another number without leaving any remainder. What am I?
Answer: Factor
Explanation: For example, 3 is a factor of 12 because 12 ÷ 3 = 4 with zero left over.

Question. Guess the Word: I am the number you get when you multiply a given number by whole numbers like 1, 2, 3, and so on. What am I?
Answer: Multiple
Explanation: Multiples of 4 are 4, 8, 12, 16, and so on—just like counting by 4s!

Question. Guess the Word: I am a special type of number that has only two factors: 1 and myself. What am I?
Answer: Prime number
Explanation: Numbers like 2, 3, 5, 7, 13, and 37 are prime because you cannot break them down into any smaller whole number factors.

Question. Guess the Word: I am an arrangement of objects into neat rows and columns that helps show factors of a number. What am I?
Answer: Array
Explanation: Lining up 20 blocks in 4 rows of 5 creates an array that shows 4 × 5 = 20.

Question. Guess the Word: I am a number that is a multiple of two or more different numbers at the same moment. What am I?
Answer: Common multiple
Explanation: Because 12 is in both the 3-times table and the 4-times table, 12 is a common multiple of 3 and 4.
