A man who attended the Alabama School of Math and Science in Mobile has moved on to big things. Specifically, on to a very, very, very big number.
AL.com's Heather Gann reports that Luke Durant has discovered the largest known prime number.
Prime numbers, you may recall, are numbers that are divisible only by themselves and 1. Six isn't a prime number because you can divide it by 2 or 3 and get a whole number. But 3, 5 and 7 are prime numbers. So are 11, 13 and 17. As you keep going higher, prime numbers are spaced out more and more so that before you know it, you're dealing with really big numbers.
Durant, who's now in San Jose, Calif., used graphics processing units, or GPUs, which are used for digital graphics and AI, to find a prime number that has more than 41 million digits.
Let that sink in. The number one trillion has 13 digits. Durant's prime number has 41 million digits.
For short, our math friends are calling the number M136279841. That name's easier to work into conversation at parties.
The discovery accomplished a few things. It might have broadened the scope of how GPUs could be used in math. If somebody discovers a use for such extremely high prime numbers, it's now known and waiting to be used. And Durant won a $3,000 research award that he said he plans to donate to the Alabama School of Math and Science.
