What is the GCF of 32 40 and 64?
To find the GCF of 3 numbers you first need to write them as their prime factors: 32 = 2x2x2x2x2 40 = 2x2x2x5 64 = 2x2x2x2x2x2 The next step is to identify any common factors. In this case, all three numbers have three 2s as prime factors. Multiply these together to find the GCF: 2x2x2 = 8 Thus the GCF of 32, 40 and 64 is 8.
