%N A110296 8-almost primes p*q*r*s*t*u*v*w relatively prime to p+q+r+s+t+u+v+w.
%C A110296 The primes p, q, r, s, t, u, v, w are not necessarily distinct. The 8-almost 
               primes are A046310. The converse, A110297, is 8-almost primes p*q*r*s*t*u*v*w 
               which are not relatively prime to p+q+r+s+t+u+v+w.
%e A110296 864 is an element of this sequence because 864 = 2^5 * 3^3, so the sum 
               of prime factors is 2 + 2 + 2 + 2 + 2 + 3 + 3 + 3 = 19 which is prime, 
               hence relatively prime to 864. That is the same sum of prime factors 
               as 640 = 2^7 * 5, hence 640 is also a member of this sequence. The 
               sum of prime factors need not be prime for this membership, for example, 
               2432 = 2^7 * 19 has sum of prime factors 2 + 2 + 2 + 2 + 2 + 2 + 
               2 + 19 = 33 = 3 * 11, which is composite, yet relatively prime to 
               2432.
