Respuesta :
The answer would be C) 2 since 2 can go into both 64 and 18 by multiplication and division.
Let's start by finding all the factors of 64 and 18.
64 / 2 = 32
32 / 2 = 16
16 / 2 = 8
8 / 2 = 4
4 / 2 = 2
This means:
64 = 2 * 2 * 2 * 2 * 2 * 2 = 2^6
18 / 2 = 9
9 / 3 = 3
This means:
18 = 2 * 3 * 3
The only factor that they both have in common is 2, so 2 is the GCF.
