How do you find the Greatest Common Factor (GCF) for an algebraic expression that contains 2 or more terms? Explain how to find the GCF of the coefficients, and of the variables. Demonstrate with an example. Be sure to address how to get the Greatest Common Factor for an algebra expression that has two or more terms. We learned in math how to find the GCF of just numbers, but here we are considering the basics of "factoring" algebra expressions, and this involves finding the GCF when variables are involved.
