What is Mersenne's number?
Primening Mersenne is a prime number that is one less than the power of two. About 44 have been discovered so far.
For many years it was assumed that all numbers of form 2 11
At that time it was clear that there was no way to test the truth about any of the higher numbers. At the same time, his peers could not prove or refute his claim. In fact, it was only a century later that Euler was able to prove that the first unproven number on Mersenne's list,2 127 89 -1 and 2 107 -1. With the advent of computers that checked whether the numbers were first -class or not much easier, and by 1947 a number of original Mersenne's primary numbers were checked. The final list added to his list 61, 89 and 107, and it turned out that 257 was not really prime. However, for his important work on the distribution of the foundation for the later mathematics from which it was possible to work, his name was given by this set of numbers. In fact, when it is 2 n - 1, it is said that it is one of the prime numbers of Mersenne. and Japrimed Number Rsenne also has a relation to thatwhat is called perfect numbers. Perfect numbers had an important place in the mystics based on the number for thousands of years. The perfect number is the number n , which equals the sum of its divisors, with the exception of itself. For example, number 6 is a perfect number because it has a divisor of 1, 2 and 3 and 1+2+3 equals 6. Another perfect number is 28, with divisors 1, 2, 4, 7 and 14. Other jumps up to 496 and another is 8128. 2 This means that in finding a new prime mersenne we also focus on finding new perfect numbers. As well as many numbers of this kind, finding a new prime Mersenne is more difficult, as we proceed because the numbers are much more complex and require much more computing forces to control. For example, while the tenth Mersenne Prime Number, 89, can be quickly checked on home computer, twenty, 4423, will tax home computer and thirtieth, 132049 requires a large number of computing power. Forty -Focked Prime Minister Mersenne, 20996011, contains more than six million individual numbers. The search for a new prime number Mersenne continues because they play an important role in a number of conjecture and problems. Perhaps the oldest and most interesting question is whether there is a special perfect number. If such a thing existed, it would have to be divisible at least eight first -class numbers and would have at least seventy -five first -class factors. One of his main divisors would be greater than 10
