Quick Worksheet: Multiples and Lowest Common Multiples (LCM)

This is a two-page PDF worksheet from Right Angle Resources designed to teach students about multiples and the lowest common multiple (LCM).

Content Overview
The worksheet is structured with definitions, examples, and practice exercises:
Understanding Multiples: This section defines a multiple and provides an example for the number 3. Students are asked to list the first ten multiples for several numbers, including 5, 4, 6, 10, 7, 9, 12, 2, and 8.

What is the Lowest Common Multiple (LCM)?: The LCM is defined as the smallest positive number that is a multiple of two or more numbers.

How to find the LCM: A three-step method is outlined: list multiples, circle common ones, and identify the smallest . An example demonstrates finding the LCM of 4 and 6, which is 12 .

Finding the LCM (Practice): Students use a table format to find the LCM for pairs of numbers: 3 and 5, 8 and 10, 6 and 9, and 12 and 16.

LCM of Three Numbers: The final section challenges students to find the LCM for sets of three numbers: 2, 3, and 4; and 5, 6, and 8.
