IntroductionIn our previous post, we talked about common multiples. Well, least common multiples or LCM is pretty much the same thing, except you just have to find the least common multiple. So, let's get started!
Least Common Multiple
In order to find the least common multiple of any numbers, you need to first know the times table of that number. However, if the number is large, you can always multiply to find its multiples!
Let's say that we have the numbers 12 and 18. Remember, we must first list its multiples:
As you can see, I have listed the first 20 multiples of both 12 and 18. Next, I will find all the common multiples and list them:
Common Multiples: 36, 72, 108, 144, 180, 216
The last step is simple: figure out the least common multiple!
The least common multiple is obviously 36.
