Students will practice finding the greatest common factor (GCF) or least common multiple (LCM) of a set of whole numbers with this Pyramid Sum Puzzle activity. In total, students will complete 21 problems (10 GCF/11 LCM).

Simply give each student the template and set of problems. They find each GCF or LCM, cut out the boxes, then paste them onto the template so that each value is the sum of the two values directly above it. **Actual answers not shown on product image.**
