C. 8
D. 12

Answer 1

The greatest common factor is the biggest number that can factor into both/all values present.
e.g. \(\text{GCF of }100\text{ and }75\) would be 25 as \(25\times4=100\) and \(25\times3=75\)

Answer 2

The gcf of 24 and 64 can be obtained like this:

The factors of 24 are 24, 12, 8, 6, 4, 3, 2, 1.
The factors of 64 are 64, 32, 16, 8, 4, 2, 1.
The common factors of 24 and 64 are 8, 4, 2, 1, intersecting the two sets above.
In the intersection factors of 24 ∩ factors of 64 the greatest element is 8.
Therefore, the greatest common factor of 24 and 64 is 8.
