CF 105424F - Наибольший наибольший общий делитель

The problem statement section is empty in your prompt, so I don’t have the actual definition of what needs to be computed (inputs, allowed operations, and what “maximum GCD” refers to in this context).

Solution

The problem statement section is empty in your prompt, so I don’t have the actual definition of what needs to be computed (inputs, allowed operations, and what “maximum GCD” refers to in this context).

For a Codeforces editorial, those details are essential because different “maximum GCD” formulations lead to completely different solutions (for example: subarray GCDs, subset selection, removing elements, pairwise optimization, or queries over ranges).

Please paste the full problem statement (or at least describe the task, constraints, and input/output format), and I’ll write the complete editorial in the exact style you requested.
