Factoring GCF in Pre-Algebra

This video tutorial by Mrs. Man covers the concept of factoring using the greatest common factor (GCF). It begins with an introduction to factoring as reverse multiplication and explains how to undo distribution. The tutorial provides steps to find the GCF and demonstrates the process with several examples. Students are encouraged to practice with problems provided in the video, reinforcing their understanding of factoring and GCF.
