# Prime Factorization Calculator

This calculator will find all of the prime factors of a natural number. Prime factorization of a number is the calculation of the primes that multiply together to give the original number. It is also known as prime decomposition.

The number 1 (one) is called a unit. It has no prime factors. When a number is a prime number (i.e., 2,3,5,7, 11), the prime factorization is just a prime number. Other numbers are called composite numbers and have a minimum of two prime factors. For repeat, a prime number is a natural number that is divisible without a remainder by itself and by a unit, not by other natural numbers.

## Practice problems:
