Optimum prime

From the SMH…

“Mathematicians at the University of California, Los Angeles┬áhave discovered a 13 million-digit prime number, a long-sought milestone that makes them eligible for a $US100,000 prize.

The group found the 46th known Mersenne prime last month on a network of 75 computers running Windows XP. The number was verified by a different computer system running a different algorithm.”

This number would be a 13mb .txt file on your computer.

From the ABC:

“Most people in Queensland don’t know what a prime number is”

…after SEVEN straight callers failed to answer the question in the afternoon quiz.

For those of you who forget:

“Primes are numbers like three, seven and 11 that are divisible by only two whole positive numbers: themselves and one.”
