The greatest common factor (GCF) of 12 and 20 is 4. To find the GCF, you need to determine the factors of each number. The factors of 12 are 1, 2, 3, 4, 6, and 12, while the factors of 20 are 1, 2, 4, 5, 10, and 20. The largest number that appears in both lists is 4, making it the GCF of 12 and 20.
