The laws of arithmetic prevent you from writing down more than 2 distinct factors of 17. They seem equally forceful, each in their own way. The laws of mathematics may be even more forceful, for it is conceivable in some physical universe you can go faster than the speed of light in this universe, it is much harder to conceive of a universe where you could write down a third factor of 17.
