To factor the expression, we have to find the greatest common factor (GCF) between the terms. Let's then rewrite each term as a product of its prime factors.
32z&= 2* 2 * 2 * 2 * 2 * z
48&= 2* 2 * 2 * 2 * 3
In this case, the GCF is 2* 2 * 2 * 2 = 16. We are going to rewrite each term as 16 multiplied by some factor. Then we will use the Distributive Property to factor the expression. Let's go!
