A number that is not prime is called a composite number. Composite numbers can be divided up into smaller whole numbers called factors. A prime number has no factors other than one and itself.
Most integers, or counting numbers, are composite numbers. Primes are comparatively rare. All even numbers are divisible by two, so they are composite numbers.
