Primes can only end in the numbers 1, 3,7 or 9 (apart from 2 and 5 of course), thus if a given ends in a 1, there should be a 25 percent chance that the next one ends in a 1 as well—but, that is not the case the researchers found. In looking at all the prime numbers up to several trillion, they made some odd discoveries. For the first several million, for example, prime numbers ending in 1 were followed by another prime ending in 1 just 18.5 percent of the time.

Primes ending in a 3 or a 7 were followed by a 1, 30 percent of the time and primes ending in 9 were followed by a 1, 22 percent of the. These numbers show that the distribution of the final digit of prime numbers is clearly not random, which suggests that prime numbers are not actually random. Cheap Mugen Chars. On the other hand, they also found that the more distant prime numbers became the more random the distribution of their last digit became.
