THE MYSTERY OF PRIMES

August 23, 2010 |  by  |  Mathematics, Mystery  |  1 Comment

Mathematicians have tried in vain to this day to discover some order in the sequence of prime numbers, and we have reason to believe that it is a mystery into which the human mind will never penetrate“. Leonhard Euler in George Simmons, Calculus Gems, 1992

Introduction

Most statements in number theory, as in mathematics as a whole, are concerned with a whole class of numbers (like class of even numbers or class of squares of integers… etc). The fundamental importance in number theory is the class of all ‘Primes’. A prime is an integer p, greater than one, which has no factors other than itself and one. An integer (other than 0 and 1) which is not prime is said to be Composite. For example, 5 is always a prime whether it is written as 5 or as the binary form 101 or in any other system of numeration. The largest known prime as of 2005 has 7,816,230 digits. The numeral 2 is the only even prime number.

            One of the first question that arise concerning the class of prime is that whether there are only a finite number of primes or infinitely many members?

Proof:             This most elegant proof was given by Euclid circa 300BC. We begin by assuming that the number of primes is finite. Let us denote them by p1, p2… pn, so that p1 = 2, p2 = 3, p3 = 5, and so on. Now consider the number

     q = p1*p2*p3* ···*pn + 1, ——— (1)

where we have multiplied together all the primes, and added with one. This integer ‘q’ cannot be a prime. Since it is larger than all n primes and ‘q’ must have a prime factor, say p, which must be one of the primes p1, p2.  . . pn. But it is clear from (1) that none of these primes divides q. This contradicts the initial assumption that was made ion the beginning that the number of primes is finite. Hence it is concluded that the number of primes is infinite.

The importance to the class of primes is due to the fact that every integer can be expressed as a Product of Primes. Any integer N greater than 1 can be factored into a product of primes n only one way. Every positive integer n can be written uniquely in the form

n = p1a1. p2a2. p3a3… pNaN.

For some choice of N, where

p1 = 2, p2 = 3, p3 = 5,… are the prime numbers. Each exponent a1, a2, a3,…aN. a1 is a nonnegative Read More
