#### Can a number be factored into a prime number?

This theorem states that natural numbers greater than 1 are either prime, or can be factored as a product of prime numbers. As an example, the number 60 can be factored into a product of prime numbers as follows: 60 = 5 × 3 × 2 × 2 As can be seen from the example above, there are no composite numbers in the factorization.
