Prime numbers are fundamentally important in mathematics and they are also very beautiful numbers. The largest known prime number we know now is 2^77232917-1 and it is a Mersenne Prime (a prime number of the form Mn = 2^n − 1 for some integer n which is also a prime number). The current largest Mersenne Prime number M77232917 (found in 2017 by GIMPS - Great Internet Mersenne Prime Search) has 23,249,425 digits. There is no website that can show you all the digits in a webpage because it is too huge. This app will generate and show you all digits of all known Mersenne Primes. You can also have close look of every digit page by page. The digits will be generated by your mobile phone's CPU and saved to your storage card. You will witness the whole process of the generation for the big ones (i.e. M77232917 , M74207281, M57885161, M43112609, M42643801, M37156667, ...), because it might need one day or two to print the digits all. You can also locate a digit by its sequence number. e.g. the 23249268th digit of M77232917 is 8.
