Answer :
If you need to find GCF, first find all of their prime factorizations.
32 = 2 * 2 * 2 * 2 * 2
48 = 2 * 2 * 2 * 2 * 3
96 = 2 * 2 * 2 * 2 * 2 * 3
Then circle any factors that all three share (the four 2's)
2 * 2 * 2 * 2 = 16.
32 = 2 * 2 * 2 * 2 * 2
48 = 2 * 2 * 2 * 2 * 3
96 = 2 * 2 * 2 * 2 * 2 * 3
Then circle any factors that all three share (the four 2's)
2 * 2 * 2 * 2 = 16.
