    It is prime only because Chuck Norris decided that it is.

        Good luck using your program on a number with over 41,000,000 digits.

        I do it with my program at least twice daily. Once I got it up to 328,000,000 digits. But I forgot to write the number down. 😞

          41,000,000 is chicken feed when compared to infinity.

          what is infinity +1? 🤔

            I bet in 100 years this will be like discovering 1+1=2. With quantum computing, such calculations should be nearly immediate. Then again maybe my expectations are too high. I'm also expecting within 20 years that AI will be able to accurately translate bird sounds into words. (no kidding)

              I had a friend who did some work translating Chinese TV/movies, etc into English captions for Netflix. That has decreased quite a bit.

              I used to do real time translation but I also see that will decrease in the future.

                Nope.

                Quantum computing, even if it ever works, won't help with finding larger primes.

                Only some very specific problems are theoretically sped up by quantum computers.

                  Yeah, computing primes is just a matter of dividing by all the possibilities and seeing if there is a remainder. And of course computers do not actually divide, they subtract a given number of times.

                    In 20 years we won’t be allowed to look for primes because of the fear of upsetting all the other numbers

                    I was only joking

                        You and @Klaus definitely know more than me about primes!

                          No, that would be way too slow. There are many many algorithms for efficient division of integer numbers, such as the Karatsuba algorithm or Newton-Raphson Division.

                            If you view numbers as ordinals, infinity + 1 is just yet another ordinal, and it is greater than infinity and smaller than infinity + 2.
