gcf, lcm and evaluating numerical expression

This resource covers the essential concepts of finding the Greatest Common Factor (GCF) and Least Common Multiple (LCM) using two different methods: the Listing Method and Prime Factorization. The document begins by explaining the GCF with a real-world example involving cookies and brownies, illustrating how to systematically determine the GCF through listing factors and comparing prime factorizations. The LCM is then introduced, accompanied by similar methods to identify common multiples, ensuring a clear understanding of both concepts. Additional sections address common mistakes to avoid during calculations and provide practice problems to reinforce these skills, making it a comprehensive learning tool for mathematics.
