Less than a year after the 43rd Mersenne prime was reported (MathWorldDecember 25, 2005), the Great Internet Mersenne Prime Search (GIMPS) project has discovered the 44th known Mersenne prime. Mersenne numbers are numbers of the form Mn = 2n – 1, giving the first few as 1, 3, 7, 15, 31, 63, 127, …. Interestingly, the definition of these numbers therefore means that the nth Mersenne number is simply a string of n 1s when represented in binary. For example, M7 = 272 is a Mersenne number. Mersenne primes are Mersenne numbers that are also prime, i.e., have no factors other than 1 and themselves. So, since the number 127 is prime and is a Mersenne number, it is a Mersenne prime. – 1 = 127 = 1111111]The Vedic Math Forum India celebrates this fact and applauds the same.
