Primes (prime number) is an integer divisible by the number one. And of itself is not perfect, so according to this definition
, it includes no specific numbers 2, 3, 5, 7, 11, 13, 17, 19, 29, 31 ..... because it has only one second to second. dividing it up perfectly or 17, there's one with 17 dividing it perfectly, but No. 15 is No. Only because 15 = 5x3, so 15 is 1, 3, 5 and 15, divided it up perfectly able mathematician. Mull that long No. Only in this universe has a number, and Euclid, the father of geometry. And as the great Greek mathematician had to prove to everyone that the universe seemed to 2,300 years ago, this number is the only number that is universal. (Infinite) the interest of mathematicians in the time to come. Trying to find a formula that will help tell. Any number is a unique number that the French mathematician Pierre Fermat. The celebrity had proposed a formula to find the number, only the No. 22n + 1 is the number specifically whether n is an integer, what, when n = 1 we will have a number of 221 + 1 = 22 + 1 = 5, a number only. (22 is the number 2 multiplied by itself two times = 2x2) and n = 2, we will have number 222 + 1 = 24 + 1 = 17, that number is only more so by replacing the n = 1, 2,. 3, 4, we will have No. 5, 17, 257 and 65 537, which was only put No. But Leonard Euler, Swiss mathematician n With five instead he has found 225 +1 = 232+ 1 = 4,294,967,297. +1 225 641x6,700,417 So it is not only because of the number 641 and 6,700,417 were able to divide it perfect formula for a specific number of other recipes include n2-n + 41 to give the number only if n is less than 41. n2-79n + 1,601 recipes and give specific numbers, when n is less than 80.
