Composite Number

 

a natural number that is not prime. In other words, a composite number is a natural number that has divisors other than 1 and itself. For example, 4, 18, and 105 are composite numbers. Every composite number can be uniquely represented as a product of prime factors. (SeeDIVISIBILITY.)
