Despite finding no specific examples, researchers have proved the existence of a pervasive kind of prime number so delicate that changing any of its infinite digits renders it composite. Take a look ...

Mathematicians are stunned by the discovery that prime numbers are pickier than previously thought. The find suggests number theorists need to be a little more careful when exploring the vast infinity ...

Prime numbers are only divisible by themselves and one. Robert Brook via Getty Images In the 17th century, French monk and mathematician Marin Mersenne developed a method to find prime numbers: values ...

Prime numbers are sometimes called math’s “atoms” because they can be divided by only themselves and 1. For two millennia, mathematicians have wondered if the prime numbers are truly random, or if ...
