Fundamental Theorem of Arithmetic

Fundamental Theorem of Arithmetic

Every composite number can be written as the product of power of primes and this factorization is unique
                                           Composite number = Product of primes

Example:
                                                          16 = 2×2×2×2
This is unique, We cannot express it in any other prime numbers

Note:

• The prime Number can be repeated in the factorization
• The order does not matter
• The prime factorization of a natural number is unique, except for the order of its factors.

Prime Factorisation Tree Form

So,                                       168 = 2 X 2 X 2 X 3 X 7
