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.
The greatest common factor of 36, 54, and 72 is 1818 2*18 = 36 3*18 = 54 4*18 = 72
GCF(36, 54, 72) = 18.
Since 36 is a factor of 72, all of the factors of 36 are common to 72.
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72.Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54.GCF (72, 54) = 18
The common factors of 36 and 54 are 1, 2, 3, 6, 9, and the GCF, 18.
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 Factors of 108: 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108 Common Factors: 1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. All of the factors of 36 are also factors of 72.

18, 36, 54, 72, 90
The common factors of 36, 72, and 90 are: 1, 2, 3, 6, 9, and 18
The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54 The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72
