The world's largest prime number has 22 million digits

A pc on the College of Central Missouri has calculated the world’s largest prime quantity, coming in at 22,338,618 digits and surpassing the earlier report by almost 5 million digits. Prime numbers are an essential element in pc encryption, although this one is “too giant to at present be of sensible worth,” in response to the Nice Web Mersenne Prime Search, a gaggle devoted to discovering uncommon prime numbers. The brand new quantity known as “M74207281.”

Dr. Curtis Cooper, a professor at UCM, volunteered the pc that discovered at present’s new No. 1, and he occurs to be a earlier prime-quantity report-holder. M74207281 is a Mersenne Prime, a category of uncommon primes discovered by multiplying two with itself for some time, after which subtracting one (2P-1). As we speak’s quantity is 274,207,281-1, for instance. That is solely the forty ninth Mersenne Prime found up to now.

Cooper is eligible for a $three,000 analysis discovery award from GIMPS. Subsequent up, the group and its volunteers hope to find a one hundred million-digit prime quantity, which might internet them $one hundred fifty,000 from the Digital Frontier Basis.
