Not being a multiple 10 was handled effectively by the negated number theoretic congruence(triple bar) relation. Problem was made relatively simple by showing, in a modular arithmetic fashion that each of the 2022 factors, represented by PI Product notion, is not a multiple of 5. This saved an immense/undoable amount of arithmetic computation!
Similar but also different was the Proof of obtaining a multiple of 10 by using only the four arithmetic operations on three arbitrary integers. This was nicely demonstrated by Carlton Banks, November 2017, at math stack exchange.
