# POLQ 1 | Lesson 3 | Practice (Finding GCDs of Monomials)

Find the GCD of the sets of terms below using the strategies (mental math, factor trees, and/or factor ladders) you used for the numbers on the last page:

a) $$4x, \, 8x^2$$

Hint: $$4x = 4 * x$$    and $$8x^2 = 2*4*x*x$$   What do the two factored forms of the monomial share? $$4x$$  is your GCD or GCF.

b) $$12x^2,\, 24x,\, 36x^3$$

c) $$32xy,\, 8x^2y^2,\, -16xy^3$$
