This math topic focuses on finding the Greatest Common Factor (GCF) from the factorizations of numbers. It involves comparing factorizations to determine the set of shared factors between two numbers. The problems typically present a pair of factorized numbers and ask students to choose the GCF from multiple options. This skill is important for understanding how numbers relate through divisibility and is a foundational aspect of arithmetic and algebra.
