the author demonstrates assuming you determined that the GCF of the expression in this example is $\displaystyle 4x^2 y$

However, shouldn't the correct assumed GCF be $\displaystyle 4x^2 y^2$? Listing the Y powers in increasing order for this expression: $\displaystyle y^2, y^3, y^5$. Since the lowest power of y is y^2 wouldnt the correct assumption be $\displaystyle 4x^2 y^2$?
