In May 2013, the mathematician Yitang Zhang launched what has proven to be a banner year and a half for the study of prime numbers, those numbers that aren’t divisible by any smaller number except 1.

Occasionally, a major mathematical discovery comes from an individual working in isolation, and this gives rise to great surprise. Such an advance was announced by Yitang Zhang six years ago. After ...

Prime numbers — those divisible only by 1 and the number itself, like 5, 11 or 37 — are like the atoms of mathematics: All numbers are formed by multiplying these building blocks together. But what ...

Prime numbers are more than just numbers that can only be divided by themselves and one. They are a mathematical mystery, the secrets of which mathematicians have been trying to uncover ever since ...

Mathematicians have been studying the distribution of prime numbers for thousands of years. Recent results about a curious kind of prime offer a new take on how spread out they can be. You may have ...

An odd new paper without peer review claims prime numbers have "genes," "roots," and “offspring." Prime numbers are essential to modern life because they underpin all of encryption. What is written ...

A new proof has debunked a conspiracy that mathematicians feared might haunt the number line. In doing so, it has given them another set of tools for understanding arithmetic’s fundamental building ...

You must have learnt about prime numbers in Class 4 or 5. Want to recall it? So, prime numbers are those numbers which are only divisible by 1 and themselves. They do not have any other factors ...
