assembly - Understanding bomb lab

Hope you can help me to understand how I can find out the six numbers. Have tried couple set of numbers that I thought was the right ones but guess I′m not understanding it right.

So for the first, this six numbers that I'm looking for, isn′t it numbers that are the outcome or the number that I put in to fit to the code?

Do I have to go through all the code or are there just few lines that I can find out these numbers? Started to think that I'm over thinking it, that it′s much easier to find those numbers then the ways I′m trying.
