Since then, prime numbers have proved to be elusive mysteries in the world of mathematics.

Any discussion on the location process for prime numbers must begin with the statement of one fact: there is an infinite number of prime numbers. All facts in mathematics must be backed by a proof, and this one is no exception. Assume all prime numbers can be listed like this: p1, p2, p3,...pN, with p1 = 2, p2 = 3, p3 = 5, and pN = the largest of the prime numbers (remember, we are assuming there …
A question one might ask at this point is "How is any of this important?" Believe it or not, theories about prime numbers play an important role in big money banking around the world. Computers use large numbers to protect money transfers between bank accounts. Cryptographers, people who specialize in creating and cracking codes, who can factor one of those large numbers are able to …
