 Composite Number:  A composite number is a number that has factors in addition to one and itself. Thus, all non-prime numbers are composite numbers.
If a number is composite, then it can be broken into smaller groups. For example, suppose a manufacturer wants to make cookies in a variety of different-sized packages. Each package of cookies will contain a certain number of cookies.

When producing cookies, the manufacturer needs to produce a composite number so that it can be divided into an equal number of sets. For example, in order to make 10 packages of 20 cookies, 8 packages of 30 cookies, and 25 packages of 4 cookies, a total of 540 cookies needs to be produced. This method works because 200 (10*20), 240 (8*30), and 100 (25*4) are composite numbers.
