One way to find the GCF is to list the factors of each number and find the largest one they have in common. The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The largest factor that they have in common is 18, therefore the GCF of 18 and 72 is 18.
