A basic feature of number theory, prime numbers are also a fundamental building block of computer science, from hashtables to cryptography.

Prime numbers are one of the most basic topics of study in the branch of mathematics called number theory. Primes are numbers that can only be evenly divided by themselves and 1. For example, 7 is ...

Prime numbers are one of the most basic topics of study in the branch of mathematics called number theory. Primes are numbers that can only be evenly divided by themselves and 1.

The Riemann hypothesis is the most important open question in number theory—if not all of mathematics. It has occupied experts for more than 160 years. And the problem appeared both in ...

The amount of prime numbers, seen as yellow dots in this hexagonal spiral of positive integers, wanes as the numbers get bigger — a relationship described by the prime number theorem and proved many ...

The twin primes conjecture is one of the most important and difficult questions in mathematics. Two mathematicians have solved a parallel version of the problem for small number systems.

Prime numbers are found hidden in nature, but humans have made spectacular use of them, writes mathematician Marcus du Sautoy.
