As Dakotakid points out, those are the most common thread patterns. You can certainly switch the can from one rifle to another, as long as the thread pattern matches if you're direct thread, or if have a common muzzle device for quick attach/detach.
Below are a few examples from SilencerCo of their "ASR" mount and associated muzzle devices. The ASR mount would go on each of your previously threaded rifles, and then you could use the same suppressor across each of those rifles very easily.
Many companies offer some sort of option like this to allow for cross compatibility.
