2023 USAJMO. Problem 1. Find all triples of positive integers that satisfy the equation. Related Ideas. Identities. Change of Variables. Factorization. Hint. Expand both sides. Changing variable: a=2x^2, b=2y^2, c=2z^2 (a-1)(b-1)(c-1)=2023. Prime factorize 2023. Similar Problems. Factorize a^3+b^3+c^3-3abc.Problem. Given a sequence of real numbers, a move consists of choosing two terms and replacing each with their arithmetic mean. Show that there exists a sequence of distinct real numbers such that after one initial move is applied to the sequence -- no matter what move -- there is always a way to continue with a finite sequence of moves so as to obtain in the end a constant sequence.
