QUESTION: 19

Which number below is a factor of 25?

Solution:

The number 25 is a composite number. Now let us find the prime factors of 25.

  • The first step is to divide the number 25 with the smallest prime factor,i.e. 2

25 ÷ 2 = 12.5

          Therefore, 2 cannot be a prime factor of 25.

  • Now, proceed to the next prime numbers, i.e. 3

25 ÷ 3 = 8.33

           Therefore, 3 cannot be a prime factor of 25.

  • Again, moving to the next prime number, 5 and continue dividing till you get fraction or 1 as the output.

25 ÷ 5 = 5

5 ÷ 5 = 1

  • We have received 1 at the end in the division process and further, we cannot proceed. So, the prime factors of 25 are 5 × 5 or 52, where 5 is a prime number
