How do you say 3747th in Spanish?

Ordinal numbers in Spanish are not easy.

If you ask the average native speaker how to say 3747th in Spanish, they will most likely respond with:

el 3747 [sic.] (tres mil setescientos cuarenta y siete)

Literally:

The 3747

The actual answer, I think, is: tresmilésimo septuagentésimo cuadragésimo séptimo.

So can our AI overlords do better?
