The three smallest prime numbers are 2, 3 and 5. It's easy to find out if small numbers are prime — one simply needs to check what numbers can factor them.

Mathematicians Hunting Prime Numbers Discover Infinite New Pattern for Finding Them Using a notion called integer partitions, mathematicians have discovered a new way to detect prime numbers while ...

For the first time in more than 25 years, mathematicians have proven a new way to identify prime numbers, and in doing so developed a toolkit that could allow further advances in number theory.

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.
