In the previous post we learned about the meaning of multiple, common multiples, and Least Common Multiple (LCM). We also learned how to get the least common multiple of two or more numbers by listing. In this post, we learn how to get the LCM of two or more numbers using the ladder method.
Find the LCM of the following numbers:
1.) 6, 9
2.) 10, 12
3.) 15, 24
4.) 3, 6, and 8
5.) 5, 6, and 7
The answers to the exercises above are available below this text. Answer the exercises above before scrolling. You may also want to proceed to the next lesson which is on getting the LCM of two or more numbers using the ladder method.
