Welcome to Mr. Ace Math! Today, we're going to explore the exciting world of multiples, specifically multiples of 4. Understanding multiples is a fundamental skill in math, and we’ll make it fun and easy to grasp. So, let's dive in!

What are Multiples?

A multiple is what you get when you multiply a number by an integer. For example, the multiples of 4 are all the numbers you get when you multiply 4 by 1, 2, 3, and so on. Here are the first few multiples of 4:

4 x 1 = 4

4 x 2 = 8

4 x 3 = 12

4 x 4 = 16

And the list goes on! Simple, right?

How to Find Multiples of 4

Finding multiples of 4 is as easy as multiplying 4 by any whole number. Let's look at a couple of examples:

Example 1:

What is the 5th multiple of 4?

Multiply 4 by 5: 4 x 5 = 20

So, the 5th multiple of 4 is 20.

Example 2:

What is the 7th multiple of 4?

Multiply 4 by 7: 4 x 7 = 28

So, the 7th multiple of 4 is 28.

Why Are Multiples Important?

Multiples help us with many math problems, especially when finding the least common multiple (LCM). The LCM is the smallest number that two or more numbers share as a multiple. Knowing how to find multiples makes it easier to solve problems involving the LCM.

Let's Find the Least Common Multiple

To find the least common multiple of two numbers, you list their multiples and find the smallest number they both have in common.

Example:

Find the least common multiple of 4 and 6.

Multiples of 4: 4, 8, 12, 16, 20, 24, ...

Multiples of 6: 6, 12, 18, 24, ...

The smallest common multiple is 12.

So, the least common multiple of 4 and 6 is 12.

Fun Fact!

Did you know? The least common multiple is very useful when adding or subtracting fractions with different denominators. It helps you find a common denominator!

Practice Makes Perfect

Now it's your turn! Try finding the multiples of 4 up to the 10th multiple. Then, challenge yourself by finding the least common multiple of 4 and 8.
