The GCF is 18.
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. Factors of 54: 1, 2, 3, 6, 9, 18, 27, and 54. Common factors of 72 and 54 (numbers that are on both lists): 1, 2, 3, 6, 9, and 18.
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
Prime factor each number. Circle the factors that are in all three numbers. Multiply those factors. 27=3x3x3 54=2x3x3 72=2x2x2x3x3 3x3=9 is the GCF
54 is 75% of 72.
This requires the highest common factor of 54 and 72. First split into prime factors: 54 = 2*(3^3) 72=(2^3)*(3^2) Multiply together common prime factors: 2*3*3 = 18 18 is the HCF of 54 and 72.
