## How to Find the Greatest Common Factor in Algebra

Finding the greatest common factor in algebra is easy.## Question

What is the greatest common factor of the terms shown below?## Step-by-Step:

## 1

Look at the number that appears in both terms.
Find the greatest common factor of these numbers. In our example, the greatest common factor of 2 and 4 is 2.
finding the greatest common factor of a number

**2**x

^{2}y

^{2},

**4**xy

^{3}

## 2

Look at the letters (and/or brackets) that appear in both terms. In our example,

**x**and**y**appear in both terms. For each letter that appears in both terms, find the letter with the smallest exponent.- Look at the
**x**terms.2**x**y^{2}^{2}, 4**x**y^{3}**x**has the smallest exponent. (**x**has an*implicit*exponent of 1 (**x**=**x**), whereas^{1}**x**has an exponent of 2).^{2} - Look at the
**y**terms.2x^{2}**y**, 4x^{2}**y**^{3}**y**has the smallest exponent. (^{2}**y**has an exponent of 2, whereas^{2}**y**has an exponent of 3).^{3}

## 3

Write the terms found in the previous

**Steps**next to each other.## Answer:

The greatest common factor of**2x**and^{2}y^{2}**4xy**is:^{3}## What Is a Factor in Algebra?

A factor is a quantity that divides exactly into a term. A factor is one of the numbers, letters and brackets (or a product of them) that are multiplied together to make a term.## What Is the Greatest Common Factor in Algebra?

The greatest common factor in algebra is the largest factor that is common to two or more terms.## Finding the Greatest Common Factor of More Than Two Terms
