**Beni**: If you consider a primitive triple (a,b,c) such that b-a divides c, then it is not hard to see that b-a = 1. Indeed, any common prime factor of b-a an...**Jean-Marie Hachey**: The least value of n for which p(n) is divisible by one million.3632530092543578593083233157739676164671583617363389322707108646070926860805348954...**ksdme**: 5977 Can be written as 5927 + 2*5^2 Where 5927 is a prime....**Missaka Iddamalgoda**: This is the code I came up with in JAVA I guess it is efficient and to find the Smallest multiple to any number you just have to replace 20 with numbe...**Laurent Jouhet**: You can test if primeSum[i] - primeSum[j] is prime without a binary search, using a classic divisibility test.
