A prime number is a whole number greater than one that has exactly two factors. Those two factors are one and the number itself. This definition is found across many school curriculums. Examples ...

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 ...

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 ...
