One way to find common factors in math is to list the factors of the numbers you're comparing.

Example: 30 and 42

1, 2, 3, 5, 6, 10, 15, 30

1, 2, 3, 6, 7, 14, 21, 42

The numbers that appear on both lists (1, 2, 3, 6) are the common factors.

The largest of these (6) is the greatest common factor, or GCF.
