Composite Number

A composite number is a positive integer that can be formed by multiplying two smaller positive integers, so it has at least one divisor other than 1 and itself. Every positive integer is either 1, a prime, or a composite number. Examples include 4, which is 2 times 2, 14, which is 2 times 7, and 360, which factors as 2 cubed times 3 squared times 5. The fundamental theorem of arithmetic guarantees that every composite number breaks down into a unique product of prime numbers.
