About this worksheet
Each worksheet has 12 problems rewriting a sum of two two-digit numbers as their greatest common factor times a sum.
Every distributive property worksheet on this site expands - it takes a times a sum and multiplies it out. This one runs the property backwards, starting from a sum and pulling the common factor out, which is a different skill because you cannot factor a sum until you can find the greatest common factor of its terms. The two numbers left inside the brackets are always coprime, so the greatest common factor is the only answer that works. Sheets can be customized, turned into flash cards, or assigned for online learning.
