Jason is trying to make picnic lunches.He has 12 sandwiches, 18 apples and 30 pieces of candy.How many lunches can he mmake if he wants each lunch to have the same number of each kind of food and use all of the food?

The only common factor is 6.
The question seems flawed, though, because 3 apples a piece seems a bit much.
