To find common factors, factor each of the two or more given numbers and select the factors common to all. Example: Find the common factors of 54, 36, and 72. Factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. Factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The common factors of 54, 36, and 72 are 1, 2, 3, 6, 9, and 18. The GCF (Greatest Common Factor) of 54, 36, and 72 is 18.
18, 36, 54, 72,...and all other multiples of 18 are divisible by 18.
-18 - 54 = -72
72 - 18 = 54 54 / 18 x100 = 300% increase
GCF(36, 54, 72) = 18.
