## Composite Number Definition

A composite number is a whole number that can be divided evenly by numbers other than 1 or itself.

A composite number n is a positive integer n>1 which is not prime (i.e., it can be divided by whole number other than 1 and itself).

• Example 1: 6 can be divided evenly by 2, so 6 is a composite number.
• Example 2: 5 cannot be divided evenly (except by 1 and 5), so is not a composite number (it is a so called prime number).
