Question

Write 63 as a product of prime factors in ascending order. I don't need the answer but the explanation as to my friends one was not enough

Answer 1

63 = 3 × 3 × 7

Explanation:

Start dividing by the smallest prime divisor till you reach 1

Which is 3

63/3 = 21

21/3 = 7

7/7 = 1

So the prime factors are: 3,3,7

Answer 2

Explanation:

63= 3 * 3 * 7

63 will come in 7th table. 7*9. here 7 is a prime and 9 is composite number. 3*3 = 9. So 63 = 3*3*7
