I'm just here to point out that since Python 3.10, you don't need to import anything from typing anymore, you could use the built-in types for annotation:

  from math      import prod
  from itertools import combinations

  def find_products(k=3, N=108) -> set[tuple[int, ...]]:
    """A list of all ways in which `k` distinct positive integers have a product of `N`.""" 
    factors = {i for i in range(1, N + 1) if N % i == 0}
    return {ints for ints in combinations(factors, k) if prod(ints) == N}

  find_products()

The typing version is still useful when you want to communicate that the result conforms to a certain interface, which doesn't include mutability in the case of Set, but not the exact type.

Edit: I see that he imported the typing Set, which is deprecated, instead of collections.abc.Set, which is still useful, so your comment is correct.
