Lesson 4 Exercise 3 - Not in scope: 'factors'

Anyone else have this issue trying the implementations for 'perfects' in ghci? I had to implement 'factors' first (easy enough, since we were shown how in the lecture):

    factors n = [x | x <- [1..n], n `mod` x == 0]

Yes, saw the same 'not in scope' issue. Thanks for posting the factors implementation here.
