Finding Greatest Common Factor (Level 2)

This math topic focuses on practicing finding the Greatest Common Factor (GCF) of pairs of numbers. It spans various pairs and offers multiple choice answers for each query to allow the student to select the correct GCF from a list of options. Each problem is set out clearly with numbers whose GCF needs to be determined, followed by a series of potential answers labeled from 'a' to 'f'. The exercise provides a fundamental understanding of how to determine the common factors between numbers, which is a critical skill in factoring within mathematics.
