Finding the Greatest Common Factor Using Continuous Division

Sheena Doria

This educational math video introduces students to finding the Greatest Common Factor (GCF) using the Continuous Division Method, also known as the Ladder Method or Upside-Down Division. Hosted by an animated teacher avatar, the lesson begins with a practical word problem involving cutting different lengths of yarn into equal strips to demonstrate real-world application. It then transitions into a step-by-step procedural tutorial on how to set up the numbers, identify common prime factors, and perform the division until no common factors remain.
