Which expression represents the greatest common factor (GCF) of 48 and 136?

A. 2 x 2

B. 2 x 2 x 2

C. 2 x 2 x 2 x 3

D. 2 x 2 x 2 x 3 x 17

The answer is B

2 x 2 = 4

4 x 2 = 8

8 x 6 = 48

8 x 17 = 136

why isn't it C or D?

For C, 8 x 3 = 24 (throwing the 8 in there because the expression is the same as B).

24 x 2 = 48, but 24 x 5 = 120 and 24 x 6 = 144.

It's also the same reason why it's not D, except that the expression goes WAY into the 400's

B

Step-by-step explanation:

C and D dont go into 48 AND 136 evenly. B is the largest one there that goes into both 48 AND 136.
