Prime numbers form the basis of most encryption algorithms, which are used to protect sensitive data such as credit card information, passwords, etc. Any natural number greater than one can be written as a product of prime numbers. The prime factorization is unambiguous, that is, for any natural number N, there is exactly one product of prime numbers. Multiplying prime factors is quick and easy. For example, the product of the two prime numbers 29 and 31 is 899. It is much harder to take 899, and find its prime factors. For very large numbers, such as 150-digit prime numbers, finding the prime factorisation is near impossible - and it is this difficulty that forms the basis of encryption algorithms.
Often times, when people speak of divisibility, they mean is it divisible with no remainder. In this case since 899 is an odd number, the answer is no. However, we can divide 899 by 2 and the result is 449.5
