Welcome to Mr. Ace Math, your go-to place for making math fun and easy! Today, we're diving into the fascinating world of **factors**. Whether you're a 3rd grader just starting your math journey or looking to sharpen your skills, this post will guide you through the basics with examples and tips. Plus, we've got some cool resources at the end, so stick around!

## What Are Factors?

Factors are numbers you can multiply together to get another number. For example, think of the number 12. If you can find two numbers that multiply to make 12, you've found its factors. In this case, 3 and 4 are factors because 3 × 4 = 12.

## How to Find Factors of a Number

Finding factors is like a treasure hunt. Let’s break it down with an easy step-by-step method:

**Start with 1**: Every number has 1 as a factor.**Find pairs**: Think of all the different pairs of numbers that multiply to make the target number.**K**eep going until you meet in the middle: Once the pairs start repeating, you’ve found all the factors.

Example 1: Finding Factors of 16

Start with 1: 1 × 16 = 16

Next pair: 2 × 8 = 16

Another pair: 4 × 4 = 16

So, the factors of 16 are 1, 2, 4, 8, and 16.

Example 2: Finding Factors of 20

Start with 1: 1 × 20 = 20

Next pair: 2 × 10 = 20

Another pair: 4 × 5 = 20

Therefore, the factors of 20 are 1, 2, 4, 5, 10, and 20.

What Are Common Factors?

Common factors are factors that two numbers share. For instance, if you want to find the common factors of 12 and 16, list out all their factors first:

Factors of 12: 1, 2, 3, 4, 6, 12

**Factors of 16**: 1, 2, 4, 8, 16

The common factors are 1, 2, and 4.

## Greatest Common Factor (GCF)

The **greatest common factor** (GCF), also known as the **highest common factor** (HCF), is the largest factor that two numbers share. Using our previous example:

**Common factors of 12 and 16**: 1, 2, 4**Greatest common factor**: 4

Knowing how to find the GCF is super useful, especially when simplifying fractions or solving problems that involve multiple numbers.
