scratch that.
is 5606701775893 a prime number?

It can be easily checked using your browser and www sites. Took me less than 10 seconds.

 

[chhitiz]

then why don't you tell me what you did find out you smug and condescending cheapo.

In hope that you will spend five minutes of your valuable time googling and learning how to do it on your own next time.

well, you are supposed to ask a question only if you have done your own research but could not find an answer. Now if you don't know about google, then I suggest you start right there and teach yourself how to use google. If you know about google, then I suggest you use it.

and criticizing the people who are trying to help you is a sure way not to get help the next time around. just my opinion as I am an opinionated person and therefore I have an opinion on just about anything.

Maybe Borek's trying to get you to solve hard questions for yourself. It would be very unethical to tell you the answer right away...

And your reaction doesn't really motivate us to help you in the future...

For someone who expects someone else to do your work for you, you're pretty brazen.

Goggle "prime number checker" I did and got over 120,000 hits. Don't know which of them are capable of checking numbers as big as 10^17 + 1 though. Try them and see. I believe that the mosty active sites are posted first though.

And what happened with 59,649,589,127,497,217 ?

And what happened with 59,649,589,127,497,217 ?

See http://oeis.org/A050922 This came up in a goggle of the number. It is a prime factor of 2^(2^n) +1 for some n and thus a well known prime.

Not for the benefit of the thread starter, but for any others: For all its failings, Wolfram Alpha had the answer in the time it took the page to refresh. The command, for those unawares, is...

factor 59,649,589,127,497,217

The pi function, unfortunately, was a complete failure for an integer this large.

For god's sake, chhitiz, what would you EVER gain by knowing whether or not that is a prime number? It's as if you typed in a random string of numbers into your keyboard.

I don't think it is random because it is a well known prime factor of a number of the form 2^(2^n) +1 which can't be said about primes in general of that order.
