Finding Greatest Common Factor (Level 4)

This math topic focuses on finding the greatest common factor (GCF) of pairs of numbers. It consists of multiple-choice questions where students must identify the GCF from a list of options for different number pairs. Each problem presents a pair of integers, and options are listed for students to choose the correct greatest common factor. This exercise is part of a broader unit on Factoring and Greatest Common Factor, aiming to strengthen understanding and application of the GCF concept in mathematical problems.
