This math topic focuses on finding the greatest common factor (GCF) of numbers using their factorizations. It involves recognizing and selecting sets of shared factors between two given numbers. This foundational skill helps in understanding the relationships between numbers and is crucial for more advanced mathematical concepts in algebra, such as factoring polynomials. Each problem requires determining the GCF from the factorizations presented in a graphic format. It is designed for introductory learning in factoring and understanding the greatest common factor.
