n! = n * (n-1) * (n-2) * ... * 3 * 2 * 1

n! = n * (n-1)!

filter_factorials([1, 2, 3, 4, 5, 6, 7]) ➞ [1, 2, 6]

filter_factorials([1, 4, 120]) ➞ [1, 120]

filter_factorials([8, 9, 10]) ➞ []

self.assertEqual(filter_factorials([1, 2, 3, 4, 5, 6, 7]), [1, 2, 6])
self.assertEqual(filter_factorials([1, 4, 120]), [1, 120])
self.assertEqual(filter_factorials([8, 9, 10]), [])
self.assertEqual(filter_factorials([1, 8, 9, 10]), [1])
