The Greatest Common Factor (GCF) of 20, 28, and 36 is 4. The factors of 20 are 1, 2, 4, 5, and 10. Since ten is not a factor for either 28 or 36, we can remove it from consideration. Five, likewise, is not a factor for either 28 or 36, so it can be removed as well. This leaves four, which is the greatest common factor for all three numbers.
