Re: Smallest sum of digits of a multiple of n

Yeah, I think I also proved that the sum of digits of any multiple of n=111..1 is at least the nunber of digits of n it in a not so formal way. I thought of using this as an upper bound for a general number, since any number coprime with 2, 3 and 5 has a (least) multiple like that. However, turns ou...

Smallest sum of digits of a multiple of n

A problem I've been thinking about for some time: Let s(n) be se sum of digits of n in base 10. It only adds once, so s(78)=15 and does not reduce further to 6 (it's not classes of equivalence modulo 9). For a given n, what's the smallest number in the infinite set S={s(n), s(2n), s(3n),...}?

Your view contradicts the cosmological principle that states that the universe is roughly the same everywhere. In your model all energy is inside a limited space, and there are regions of infinite size with nothing in them (though I guess that wouldn't take into account dark energy and dark mass).
