North Canton supercomputer verifies world's largest prime number
NORTH CANTON, Ohio -- A computer science professor at the University of Central Missouri this month found the largest prime number ever discovered, at 22 million digits long.
That prime number -- divisible by only 1 and itself -- was verified this week by a supercomputer at Squirrels, a software development company in North Canton.
It is the first world record breaking number since 2013 and was discovered as part of a network of computers strung together around the world through a collaborative called GIMPS, or Great Internet Mersenne Prime Search.
Once the algorithm, run since 1996, finds a prime number, the group delegates to a member with a more powerful computer to verify that the new, really long number is actually prime. That job went to David Stanfill, president of Squirrels and a participant in the GIMPS program.

Here is how the new prime number is written mathematically for the nerdy types that have absolutely nothing better to do than multiply for the next few days: 274,207,281 - 1 .
