List the factors.
1, 2
1, 2, 3, 4, 6, 12
The largest number on both lists is 2, the GCF
The GCF is 2.
The GCF is 2.
The GCF of 84 and 156 is 12.First, find the prime factors:84 = 2*2*3*7156 = 2*2*3*13Then, to determine the gcf, multiply the shared prime factors:GCF = 2*2*3 = 12
You need at least two numbers to find a GCF.
The GCF is 2.
The same as the gcf of 12 and 2. (2 is the remainder of the division of 74 by 12.)
The GCF of 12 and 54 is 6. To find the GCF, write the prime factorizations of each number.The prime factorization of 12 is 2*2*3The prime factorization of 54 is 2*3*3*3The factors in common are 2*3 = 6, so that is the GCF.
The GCF of 6, 12 and 2 is 2.
