What is the GFC of16 32?

Answer 1

To calculate the GCF you first need to split the numbers into their prime factors:

16=2x2x2x2

32=2x2x2x2x2

The next step is to identify the common factors in each. Both numbers use four 2s, so we take these 4 2s and work out the product:

2x2x2x2=16

Thus, the GCF of 16 and 32 is 16.
