Finding the Greatest Common Factor

This video introduces factoring, emphasizing the importance of prime factorization and the greatest common factor (GCF). It explains prime factorization using factor trees and demonstrates finding the GCF of numbers and variables. The video concludes with factoring expressions by extracting the GCF and identifying the 'leftovers'.
