Answer
$7x^3y^3z^3\cdot (7xz^2- 10y^2z+5xy)$.
Work Step by Step
The given expression is
$=49x^4y^3z^5-70x^3y^5z^4+35x^4y^4z^3$
The GCF of the given expression is $7x^3y^3z^3$.
Factor the GCF.
$=7x^3y^3z^3\cdot 7xz^2-7x^3y^3z^3\cdot 10y^2z+7x^3y^3z^3\cdot 5xy$
Factor out the GCF from each term.
$=7x^3y^3z^3\cdot (7xz^2- 10y^2z+5xy)$.
