The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.

The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 60, and 120.

The greatest common factor is 6.

The other method to find the greatest common factor is to find the prime factorizations of each.

42: 2-3-7

120: 2-2-2-3-5

By taking all the ones that appear from both lists (2 and 3 only), the greatest common factor is found by multiplying (6).
