Least Common Multiple

Click on the image at right to get the lesson app with instructor notes.

In this lesson, students will learn how to determine the least common multiple of two numbers by dividing the product of the numbers by their GCF. Students will briefly explore the proportional relationship between the LCM and GCF of two numbers. This relationship will be introduced with a bit of algebraic notation.

Video

In this video, multiple, common multiple, and least common multiple are defined with an example. There is no greatest common multiple. The method of multiplying two numbers and dividing by their GCF to get their LCM is mentioned.

You can have students raise and discuss questions about the video and allow students the opportunity to work through one or two different examples they can think of (different number pairs).
