Numbers for OS 12.7.6

The Mac App Store requires Sequoia, macOS 15. or later to install the current version of Pages & Numbers.

You can get the last compatible version of Pages or Numbers for your OS, provided you have installed Pages or Numbers previously from the Mac App Store and using the same Apple ID. If you haven't, or the Mac had Pages or Numbers preinstalled, then there is no easy means to get any version of Pages or Numbers now.

Launch the Mac App Store. Sign in with your Apple ID. Press cmd+0 (zero) to open the Purchases panel, and if Pages is there with any indication that it can be installed, then click that. Do not Cancel any subsequent dialogs and this may result in your having the last compatible version of Pages or Numbers for your version of macOS.

macOS Monterey version 12.7.6 was released over two years ago. The current version of Numbers cannot run under macOS Monterey. So if you never downloaded an earlier version of Numbers, you’re out of luck while using macOS Monterey.
