Finding the LCM Using the Ladder Method

The video tutorial explains how to find the least common multiple (LCM) using the ladder method, also known as the division method. It provides step-by-step examples for finding the LCM of pairs of numbers: 4 and 10, 18 and 45, 12 and 18, and 30 and 40. The tutorial emphasizes that different shared factors can be chosen, but the LCM result will remain the same. The video also includes practice problems for viewers to solve on their own.

Explain the process of finding the LCM of 12 and 18.

What is the final LCM of 30 and 40, and how did you arrive at that answer?
