Prime Factorization

Concept

Prime Factorization

Whole numbers which are not a prime number are called a composite number. These numbers can be divided into a product of two, or more, lower whole numbers. 12=34. 12 = 3 \cdot 4. The procedure can then be repeated until 12=322. 12=3 \cdot 2\cdot 2. All composite numbers can be factored into primes in only one way. This relationship ties together all whole numbers in a fundamental manner which is why it is called the Fundamental Theorem of Arithmetic.
