# Finding Factors

In this lesson, students will find the factors of the numbers listed in the worksheet.

First, you will copy the worksheet so that each student will have a copy.

Then, you will explain about factors. Factors are numbers that you multiply together to get a product.

Here's an example: Factors of 24

12 x 2 = 24

6 x 4 = 24

1 x 24 = 24

3 x 8 = 24

Factors: 1, 2, 3, 4, 6, 8, 12, 24

After that, you will pass out the worksheets so the students can work on them independently.
