A prime number is a natural number greater than 1 that has exactly two distinct factors, 1 and the number itself. So, if p is a prime number then its only factors will be 1 and p itself. 4: It can be ...

For centuries, prime numbers have captured the imaginations of mathematicians, who continue to search for new patterns that help identify them and the way they’re distributed among other numbers.

A shard of smooth bone etched with irregular marks dating back 20,000 years puzzled archaeologists until they noticed something unique – the etchings, lines like tally marks, may have represented ...

Prime numbers are beautiful and fascinating – and an infuriating puzzle. Easy to define, yet rowdy and disordered, the primes have no evident pattern. The more of them you list, the more erratic they ...

Prime numbers, vital in mathematics and competitive exams, can be quickly identified using a systematic approach. This method involves checking divisibility by primes up to the square root of the ...

It's videos like this one from YouTube user Numberphile that make us mortals realize why mathematicians view math as art, or perhaps as power. Highly composite numbers—numbers that have more divisible ...

Digitally delicate prime numbers become composite with this one weird trick. Math researchers proved these primes exist using the bucket proof method. There are no known examples so far, but ...

The online computer game “Is this prime?” tests a player’s knowledge of prime numbers—and just surpassed 2,999,999 attempts. Give it a whirl. The Greek mathematician Euclid may very well have proved, ...
