%N Greater term of smallest primitive friendly pair such that both terms are divisible by the n-th prime p and coprime to the primes below p.

%C By definition, GCD(a(n), A002110(n-1)) = 1. - _Michel Marcus_, Jan 19 2014

%e For n=1, the perfect numbers 6=2*3 (A214132) and 28=2^2*7 are primitive friendly.

%e For n=2, 135=3^3*5 (A214132) and 819=3^2*7*13 are primitive friendly.
