For this case we have that by definition, the Greatest Common Factor (GCF) is the largest factor that 2 numbers have in common.
So, we have the following expressions:

We look for the positive integers that divide to 35 and 42 without leaving residue:
42: 1,2,3,6,7,14,21
35: 1,5,7
Thus, the GCF of 42 and 35 is 7
Then, the GCF of the three expressions is:

Answer:
D. 900 in ^3
Step-by-step explanation:
The volume of rectangular pond would be equal to the priduct of its height, width, and depth.
Volume = Length × Width × Depth
We are given
length = 15 inch
Width = 20 inch
Depth = 3inch
Volume = 15 × 20 × 3 = 900 in ^3
