First, prime factor all of the numbers. Then, collect the factors which appear in all three lists:
28 = 2 x 2 x 7
48 = 2 x 2 x 2 x 2 x 3
64 = 2 x 2 x 2 x 2 x 2 x 2
The only factor which appears in all lists is 2. It appears twice in the first number, so the greatest common factor in the group is 2 x 2  = 4

Hi! :)
You didn't provide any numbers, but the formula to find volume of a rectangular prism is:
V = L × W × H
V = volume
L = length
W = width
H = height
Hope this helps!
