The LCM of 4, 9 and 3 is

I'm going to show you 2 methods in which you can get the LCM in this explanation. So let's begin!

Method 1: Write down multiples of 4, 9 and 3.

4, 8, 12, 16, 20, 24, 28, 32, 36, 40

9, 18, 27, 36, 45, 54, 63, 72, 81, 90

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39

If you don't get a common number soon, then write down more multiples. Or you can quit Method 1 and move onto Method 2.

Speaking of Method 2, now you're going to learn about it!

Method 2: Write down multiples of 9. Just 9. So you're pretty much picking the largest number out of 4, 9 and 3.

9, 18, 27, 36, 45, 54, 63, 72, 81, 90

Now pick a number out of 3 and 4. Then see if that number goes into any multiple. Tip: Start from the first multiple and move on. I picked 4. Does 4 go into 9? Nope.

Does 4 go into 19? Nope.

Does 4 go into 27? Nope.

Does 4 go into 36? Yes!

Now, does 3 go into 36, too? Yes!

You already know that 9 goes into 36 because it is a multiple of 9! So, the LCM will be

I hope at least one of the methods that I showed you will help you!

My source is my mind, for the methods.

All the best,

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
