It seems there's a problem with the submission tests here. The last test asks for the first number with 10 factors and expects a return of 120 but if you print n it shows that it actually asks for 9 factors and and a return of 120 meaning the algorithm for solving this will return an incorrect value.
Missile is spelt wrong in the kata description:
"tactics": ["missle", "missle", "missle", "missle"]
