DOWNLOAD AND PUT IN TURBO SPEED FOR BEST RESULTS In the past I have seen many a project like this but I think I can say that this is one of the fastest finding 242 primes and testing 1543 numbers in a minute on turbo speed. If anyone is willing to leave it on overnight and tell me the result it would be interesting to find the largest prime, how many numbers it tested and how many primes it found. Please click love-it and comment.
