The GCF of 12 and 18 is 6.

One way to determine the greatest common factor is to find all the factors of the numbers and compare them.

The factors of 12 are 1, 2, 3, 4, 6, and 12.

The factors of 18 are 1, 2, 3, 6, 9, and 18.

The common factors are 1, 2, 3, and 6.

Therefore, the greatest common factor is 6.
