Answer:
The GCF of 48 and 64 is 16
Explanation:
To figure out GCF, you make a list of all the prime factors, pick out the numbers they have in common, and multiply them together. In this case:
48: 2 x 2 x 2 x 2 x 3
64: 2 x 2 x 2 x 2 x 2 x 2
They have four 2's in common, so you multiply 2 x 2 x 2 x 2 =16
