16987...14751 (12837064-digits)
This number is a prime.
The third largest known prime number
(242643801-1); first found by a machine on April
12, 2009. It is odd that no human took notice of this fact
however until the following June 4! It is credited to Odd
Magnar Strindmo from Melhus, Norway, who has been part of
GIMPS since it began. This 47th known Mersenne prime is
only 141125 digits (just over 1%) shorter than the largest known
prime at that time.
