Yow! We Have A New Prime Number, And Itís 23 Million Digits Long

Somewhere out there on the number line, huge prime numbers are lurking, waiting to be discovered. On Wednesday, a new one was. The Great Internet Mersenne Prime Search, an organization devoted to doing exactly what its name suggests, announced that it had discovered a new prime number, the largest ever found: 2^77,232,917−1. Thatís more than 77 million 2s all multiplied together, minus 1. Iíd write it all out for you, but thereís a big problem: Itís 23,249,425 digits long.

So it takes up about as much space on a computer as a typical modern uncompressed digital image.

Well, yes, in its uncompressed form it's under 9.7 megabytes. Compressed, it's less than half the size of the average e-mail address: 2^77232917-1 (or 1<<77232917-1 or M77232917).
