# Express 60 as a product of it’s prime factors. As we know that 60 is a whole number and a composite number (divisible by more than 2 numbers). Let us find the prime factors of 60 by the following method.

1st step – Divide 60 with its smallest prime factor, which is 2

Result:-  60/2 = 30

2nd step – We need to see if 30 is further divided by 2?

Result:- 30/2 = 15

3rd step – Check if 15 is further divisible by 2

Result:- 15/2 = 7.5

Things to remember – Prime factors cannot be in decimal or fractions. It should be a whole number. So, we proceed to the next prime number i.e., 3

4th step – Divide 15 by 3

Result:- 15/3 = 5

5th step – Now, we know that prime factor should be in whole number. So, if we divide 5 by 3, it will give us a decimal or fraction. So again, we take the next prime number which is 5

Result:- 5/5 = 1

Now, we just got 1 at last. We cannot divide and calculate prime factors further because multiple of 1 is 1
