 2016-09-19, 17:55 #1 IeatPyhons   Sep 2016 110 Posts Funny looking number First off, i'm sorry if this is the wrong location for this; But it seemed right by the name. So, today i was messing around in python with the prime i got "77536897". I decided to do some test with my low-end prime program i wrote. I realized that 7753689^7 gave me 1684839914110098939787407853082536973852201202729 which in itself is too a prime number. Both 7753689 and 7536897 are too prime numbers. My program was not able to find 7^7536897. But i am sure that anyone may find interest in this number as i have. i will look for other numbers as well to insure not just a glitch in the matrix... i just did some little investigation on 7536897^7, which ironically gave me 1381491004566552667414465552862865977844679968513. ANOTHER ONE

77536897 is indeed a prime.

7753689 is not a prime, it is 3^2 * 31 * 27791.

7753689^7 is certainly not a prime -- in general n^7 is never a prime for any integer n.

Similarly, 7^7536897 is not prime -- it's divisible by 7.

There is not much hope of reaching a rational argument. Jacob * The huge fonts, the claim that an integer elevated to an integer power would be prime... It even looks more like a troll, who are to be fed, than a crank.

Drivel. By definition, n^7 is composite (assuming n>1) because it has the factorization n*n*n*n*n*n*n.

In my own experience I'd say around 2-5%. It's not much, I agree.
