B.
2x3

C.
4x3

D.
2x4

Answer 1

first, do the "number" part
4 is 2*2
14 is 2*7
what number divides into both 4 and 14 ?

Answer 2

2

Answer 3

i think the answer is B

Answer 4

yes, 2 divides into 4 and into 14
so 2 should be part of the answer.
for the x part
remember
x^3 means x*x*x
and x^6 means x*x*x*x*x*x (x times itself 6 times)

remember x divides into itself (think of x as "some number")
what divides into both x^3 and x^6
hopefully you see x divides into both
but also x^2
and also x^3

Answer 5

the biggest thing we can divide is 2 (for the number part) and x*x*x for the x part.
