How do I leave a group conversation politely in English?

Give one short reason for going, one warm line about the conversation, and no request.

The reason should belong to your day: I'm going to head off — early start tomorrow. If you want to see them again, leave a hook: I'm at the Thursday run most weeks — if you're ever there, say hi.

The wording changes with what you are actually leaving. Leaving the group: “I'll let you all carry on.” Leaving one person inside a group: “Anyway, I'll let you two talk.” Leaving the whole event, where you may want to thank a host: “I'm heading off — thanks for organising this.” Do not add a new question on the way out; it gives the other person a reason to hold you in the conversation you are trying to end.
