Finding the GCF Using Division

The video tutorial teaches students how to find the greatest common factor (GCF) of numbers using the continuous division method. It begins with an introduction to the concept of GCF and explains the steps involved in finding it. The tutorial includes example problems, such as determining the GCF of yarn lengths and the numbers 12 and 48, to illustrate the process. The video concludes with a recap of the key points learned.
