thanks for the explanation! I also remembered that the euclidean gcd algorithm is very similiar to the described process. (Just substract b to a until a turns a % b, and then viceversa)

please someone explain to me in problem: 2008G — Sakurako's Task. Why the gcd of all numbers is the key, I cant see the idea behind.

Always getting out of your comfort zone. And focusing on fixing your mistakes.
