The (k-2)nd power multiplied by the decremented p-1 of the smallest prime factor and divided by the product of the decremented other prime factors defines a(n): a(n) = (N-1)^(k-2)*(p-1)/( (q-1)*(r-1)*...). - _R. J. Mathar_, Dec 16 2010 %e A164946 The 4 factors of the first member of A104017 (11305) are 5, 7, 17 and 19. Hence the first term of the present sequence is (4*11304^2)/(6*16*18) = 295788. %Y A164946 Cf. A104016, A104017, A162290. %K A164946 nonn %O A164946 1,1 %A A164946 _A.K. Devaraj_, Sep 02 2009
