Go to Settings->Properties->Contact Properties and search and click on the Contact Owner Property. On that screen, it will list your contact owners (users) and their internal value (user ID.)
@chinhd, I just wanted to clarify that HubSpot user IDs and owner IDs are slightly different:
Properties with the "HubSpot user" field type return ownerId values, the same as returned from the Get owners endpoint. Owner ID values are used to associate CRM objects.
HubSpot user IDs are usually not surfaced in-app. They're tied to a user's login identity and are returned in the activeUserId and remoteId fields from the Get owners endpoint. The only API applications I can think of for user IDs involve OAuth tokens and CRM Extensions.
