CBSE Class 4 Maths Factor Worksheet

Q1) Write T for True and F for False statements.

• 2 is a factor of 13. [ F ]
Answer: False
In simple words: 13 is an odd number and cannot be divided evenly by 2.

Exam Tip: A number is a factor of another only if it divides the number completely without leaving any remainder.

• 17 is a factor of 17. [ T ]
Answer: True
In simple words: Every non-zero number is a factor of itself.

Exam Tip: Remember that any number divided by itself gives a quotient of 1 with a remainder of 0.

• 3 is a factor of 18. [ T ]
Answer: True
In simple words: Since \(3 \times 6 = 18\), 3 divides 18 completely.

Exam Tip: Check multiplication tables or use division to verify if the remainder is zero.

• 5 is a factor of 198. [ F ]
Answer: False
In simple words: 198 does not end in 0 or 5, so it cannot be divided by 5.

Exam Tip: Divisibility rule for 5: A number must end in 0 or 5 to be divisible by 5.

• 9 is a factor of 36. [ T ]
Answer: True
In simple words: Since \(9 \times 4 = 36\), 9 is a factor of 36.

Exam Tip: Memorizing basic multiplication facts helps in quickly identifying factors.

• 8 is a factor of 54. [ F ]
Answer: False
In simple words: \(8 \times 6 = 48\) and \(8 \times 7 = 56\), so 54 is not in the 8 times table.

Exam Tip: If a number is not a multiple of another, it cannot be its factor.

• 1 is a factor of 1999. [ T ]
Answer: True
In simple words: 1 is a factor of every whole number.

Exam Tip: Always remember that 1 is a universal factor for all numbers.

Q2) Write all the factors of given numbers
Answer: See the complete factor table below.

Exam Tip: Always list factors in pairs (e.g., \(1 \times 12 = 12\), \(2 \times 6 = 12\), \(3 \times 4 = 12\)) to ensure you do not miss any.
