# Composite Numbers

###### This wiki is incomplete.

A **composite number**, in contrast to prime numbers, is a positive integer greater than 1 that has more than 2 positive divisors. For example, 4 is a composite number because it has 3 positive divisors: 1, 2, and 4. In other words, 4 can be written as a product of more than one pair of positive integers: $4 = 1 \times 4$ AND $4 = 2 \times 2$.

All positive integers greater than one are either prime or composite.
