Mrs. Post and her kids, Hayden and Hallie, play a curveball game to review what prime and composite numbers are. Rise and Shine is available to stream on pbs.org and the free PBS App, available on ...

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 ...

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 ...

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.

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.

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 ...

Computing prime factors may sound like an elementary math problem, but try it with a large number, say one that contains more than 600 digits, and the task becomes enormously challenging and ...
