Solution

Receiving A and I, we want to find x, such that ceiling(x/A) = I, where x is as low as possible. Since the value is always rounded up, we can calculate A * I - 1, and add 1, since we calculate the "impact factor" one lower, and add a single scientist to it, which will result in the impact factor specified.
