The answer provided to the question stem is very detailed and helpful for the approach given.

With that, can you help me to understand whether there is a non-brute force approach that can be taken.

Zoinks, what a question. Frankly, I don't see another way to do it aside from the strategy that is outlined. My only two cents on this one would be that if you have to guess, guess higher. The number of solutions of this type of problem tends to be on the higher side, since there are usually some that the average test taker does not consider.
