Hello, I am trying to find an efficient algorithm to get the following information. Find A, B given integer N >= 1 where 8N = (A * B) + A and ABS(A  B) is the minimum value given N. Does anyone have any pointers, or has seen a similar algorithm out there? It is similar to factorization algorithms, but the + A portion is throwing a wrench in my ideas.

$\displaystyle ab + a = a(b+1)$ So you can use factorization.
