This math topic focuses on finding the greatest common factor (GCF) of numbers based on their factorizations. It involves recognizing the shared factors among given sets of numbers and selecting the highest common factor. The questions provide the factorizations of pairs of numbers, and learners must identify the GCF from a list of options. This is a part of a broader practice unit on factoring and understanding of greatest common factors, suitable for reinforcing skills in factor recognition and multiplication.
