What 2 numbers times together make 63?

To answer this question, you first need to break the number down into its prime factors:

63 = 3x3x7

To find two numbers that multiply to make 63, one number must be the product of some of these primes, and the other must be the product of the rest (you can also use 1). Thus the possible pairs are:

1x63

3x21

7x9
