Mathematical language can often seem to complicate simple operations. In this lesson a definition for the term divisor will be presented along with an example that makes a complex word seem quite simple.

What Is A Divisor

The word divisor sounds complicated, but it really isn't. In fact, you've probably understood the concept of a divisor since you were a child. The language is much more challenging than the actual concept.

By definition, a divisor is a number by which another number, a dividend, is divided.

This definition introduces a new term that needs to be understood before proceeding. A dividend is a number that is to be divided by a divisor.

So, we have two numbers, a dividend and a divisor. The dividend is the number divided by the divisor.

Let's look at a basic example in order to better understand the vocabulary.


Suppose you regularly attend a book club on Wednesday nights. It is your turn to bring the snack for the evening. You spent some time in the kitchen and made 28 delicious cupcakes. There are 7 people in your club and you want to make sure everyone will have enough to eat, so you decide to calculate the number of cupcakes each person will be able to eat if they were divided evenly.
