This math topic focuses on practicing how to find the greatest common factor (GCF) of two numbers using Venn diagrams for visualization. Students will apply their knowledge in factoring to deduce the GCF for different pairs of numbers. These problems serve as an introductory level for the broader subject of factoring and understanding the greatest common factors. Each question provides a set of numbers and requires the use of factor diagrams to identify the GCF, reinforcing basic factoring skills in an engaging way.
