Find the factors of 42 showing explain your work and this is the factor pairs in a table

Fundamental Theorem of Arithmetic states that every positive integer can be factor into a product of unique primes.

42=2*3*7

therefore all factors of 42 are all the combinations of the product

2, 3, 7, 6, 14, 21

and 1,42 in case you wanted to include them as well.

1,2,3,6,7,14,21, and42
