Actor Out the Greatest Common Factor $40 x^{8} y^{8}-48 x^{3} y^{6}-56 x^{6} y^{2}$

actor out the greatest common factor. Simplify the factors, if possible
- $40 x^{8} y^{8}-48 x^{3} y^{6}-56 x^{6} y^{2}$

A) $x^{3} y^{2}\left(40 x^{5} y^{6}-48 y^{4}-56 x^{3}\right)$
B) $8\left(5 x^{8} y^{8}-6 x^{3} y^{6}-7 x^{6} y^{2}\right)$
C) $8 x^{3} y^{2}\left(5 x^{5} y^{6}-6 y^{4}-7 x^{3}\right)$
D) $8 x^{3}\left(5 x^{5} y^{8}-6 y^{6}-7 x^{3} y^{2}\right)$
