actually only 3 hints will do.
all the permutations that give the product (72) give unique sum except for:
6*6*2 =14...(1)
and 8*3*3 = 14...(2)

since the friends say: the information about sum (house no.) is not enough, it means the answer must be one of those two(1) and (2) else he wouldn't need 3rd hint in the first place.
