We know that any integer greater than 1 can be formed by multiplying Prime numbers together. For example,

6 = 2 × 3

14 = 2 × 7

16 = 2 × 2 × 2 × 2

So, they are the multiplication of prime numbers together.

**Definition of Theorem**: *Every composite number can be expressed as (factorized) a product of prime numbers, in exactly one way, irrespective of the order of the multiplication. This theorem is also called the unique factorization theorem.*
