For this case we have the following expressions:

[tex] 72x ^ 2y

18xy
[/tex]

The biggest common factor for each expression is given by:

[tex] 72x ^ 2y = 18xy (4x)

18xy = 18xy (1)
[/tex]

Therefore, the biggest common factor is the one that is repeated in both terms.

We have then that for this case is:

[tex] 18xy
[/tex]

Answer:

the greatest common factor of 72x ^ 2y and 18xy is:

D. 18xy
