How to Find the Greatest Common Factor Using the Ladder Method

In this video tutorial, Suzie from Math Defined explains the concept of the greatest common factor (GCF) and demonstrates how to find it using the ladder method. The video begins with an introduction to the GCF and a review of factors, followed by several examples using the ladder method to find the GCF of different pairs of numbers. Suzie emphasizes that the GCF is always less than or equal to the numbers in the set, and she provides step-by-step instructions for each example.
