$$\left. \begin{array} { l } { a ^ { 4 } b - a b ^ { 2 } } \\ { 7 a ^ { 7 } - 56 d ^ { 4 } } \end{array} \right.$$
$7ab\left(a^{3}-b\right)\left(a^{7}-8d^{4}\right)$
$$7a^{7}-56d^{4}=7\left(a^{7}-8d^{4}\right)$$
$$7ab\left(a^{3}-b\right)\left(a^{7}-8d^{4}\right)$$
$$56ab^{2}d^{4}-7b^{2}a^{8}+7ba^{11}-56ba^{4}d^{4}$$
