{{Wikidata ID|P3634|P350|qid=Q19912922}}

which returns:

: 197003
: 436634

If you want to hide the ID, then use:

{{Wikidata ID|P350|P3634|qid=Q19912922|showid=no}}

which returns:

[1]
[2]

Ordering is new lines by default, but you can change it to commas using:

{{Wikidata ID|P350|P3634|qid=Q19912922|separator=comma}}

which returns:

: 197003, : 436634
