This math topic involves practicing finding the greatest common factor (GCF) of two numbers using Venn diagrams. Specifically, students are presented with problems where they use factor diagrams to determine the GCF. The skill practiced is critical in understanding how to break down numbers into their prime factors and finding the highest factor that is common between them, using visual aids to enhance comprehension and retention. This is part of a broader unit on factoring and greatest common factors.
