List the factors.
1, 2
1, 2, 3, 4, 6, 12
The largest number on both lists is 2, the GCF
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
The GCF is 2.
The GCF is 2.
You need at least two numbers to find a GCF.
The GCF is 2.
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 same as the gcf of 12 and 2. (2 is the remainder of the division of 74 by 12.)
