As Maarten already said, 1 is not prime. Also, note that the empty product
equals one:

Well, considered as an integer, this is giving the prime (power)
decomposition of 1. And there are no such primes, so the list is
empty.
I suppose the problem you're encountering is that what is returned
isn't a
