Any whole number that is not a prime number is a composite. All even numbers, except the number two are composites, as they are divisible by two. Prime factors of a number are useful in finding the least common denominator in a fraction. They are also helpful in determining the greatest common factor of a number. The larger a number, the greater the chance it is a composite.
