## Examples of Factors

### Example 1

Find the factor of

First, we will find the numbers that multiplied together will result to

Let’s start with times is equals to

Then, times is

Therefore, the factors of are:

### Example 2

Find the factors of

First, we will find the numbers that multiplied together will result to

Let’s start with times is equals to

Then, times is

And lastly, times is

Therefore, the factors of are:

## Examples of Greatest Common Factor (GCF)

### Example 1

GCF of and

First, list the factors of and

Now we have,

Therefore, the Greatest Common Factor is

### Example 2

GCF of and

First, list the factors of and

Now we have,

Therefore, the Greatest Common Factor is

## Examples of Multiples

### Example 1

Multiples of

In order to find the mutiples, we must multiply by an integer (not a fraction)

Therefore the multiples og are ,…..

### Example 2

Multiples of

In order to find the mutiples, we must multiply by an integer (not a fraction)

Therefore the multiples og are ,…..

## Least Common Multiple (LCM)

### Example 1

Least Common Multiple (LCM) of and

First, list down the multiples of each number

Then, the first mutiple that occurs on both numbers is the LCM

Therefore, the LCM is

### Example 2

Least Common Multiple (LCM) of and

First, list down the multiples of each number

Then, the first mutiple that occurs on both numbers is the LCM

Therefore, the LCM is
