Any positive integer can be expressed as a product of primes, repeated if necessary.
This factorization is unique.
1) 30 = 2 x 3 x 5
2) 100 = 22
3) 3600 = 24
The theorem can, formally, be stated as:
If N is any positive integer, p's are distinct primes and a's are non-negative integers;
then every number N, can be written as
