It provides an approximation for the number of primes less than a given number n, which is approximately n/ln(n). Divisibility A fundamental concept in number theory is divisibility. A number a is said to be divisible by another number b if the division a/b yields an integer without a ...
Number theory - Prime, Distribution, Theorem: One of the supreme achievements of 19th-century mathematics was the prime number theorem, and it is worth a brief digression. To begin, designate the number of primes less than or equal to n by π(n). Thus π
Computers have also been used to test solutions, with the first 10 trillion nontrivial solutions shown to lie on the critical line. A proof of the Riemann hypothesis would have far-reaching consequences for number theory and for the use of primes in cryptography. The Riemann hypothesis has ...

Mersenne prime, in number theory, a prime number of the form 2n − 1 where n is a natural number. These primes are a subset of the Mersenne numbers, Mn. The numbers are named for the French theologian and mathematician Marin Mersenne, who asserted in the preface of Cogitata Physica-Ma...
