Hi Guys! I hope all of you are fine :) Maybe someone can tell me here how can I find with Wolfram Alpha or Mathematica the nth's of larger primes? I used "PrimePi", but "PrimePi" works not with large primes (primes like these 1921773217311523519374373 do not work...too large...). Is there a criterion, method and or a script with which I can find the nth's of larger primes?
I have also used the "nthprime" function, but i think this is not what i need, but when there is a method with the nth prime function to find the "th's" of larger primes, can someone here show me, how it works? To better understanding what i mean, here an example:
- 2 is the 1(<-i need this number).Primenumber
- 3 is the 2(<-i need this number).Primenumber
- 5 is the 3(<-i need this number).Primenumber
- 7 is the 4(<-i need this number).Primenumber
and so on...another example:
19 is the 8th (!) Prime, 23 is the 9th (!) Prime, 29 is the 10th (!) Prime... now i need a function to find which prime is 1921773217311523519374373? I need a function to get that out, i hope anybody here has an idea how can i find with WolframAlpha or Mathematica which/what (!) prime is 1921773217311523519374373.
I hope anyone can help me here. Kind regards and best wishes.
