As the set of natural numbers N = {1, 2, 3, } proceeds, however, prime numbers generally become less frequent and are more difficult to find in a reasonable amount of time. 20359 20369 20389 20393 20399 20407 20411 20431 20441 20443 80651 80657 80669 80671 80677 80681 80683 80687 80701 80713 3001 3011 3019 3023 3037 3041 3049 3061 3067 3079 42751 42767 42773 42787 42793 42797 42821 42829 42839 42841 For every prime number p, there exists a prime number p' such that p' is greater than p. This mathematical proof, which was demonstrated in ancient times by the Greek mathematician Euclid, validates the concept that there is no "largest" prime number. 6481 6491 6521 6529 6547 6551 6553 6563 6569 6571 So 7 is prime. 4861 4871 4877 4889 4903 4909 4919 4931 4933 4937 102953 102967 102983 103001 103007 103043 103049 103067 103069 103079 To take a concrete example, for N = 10 22, 1 / ln ( N) is about 0.02, so one would expect only about 2 % of 22 -digit numbers to be prime.
