A positive integer is **composite** if it is neither prime nor equal to 1. The smallest composite is 4.

If a number can be written as the product [math]\displaystyle{ a * b }[/math] where the integers [math]\displaystyle{ a }[/math] and [math]\displaystyle{ b }[/math] are both greater than 1, the number is composite.
