@peterrowlett I mean it's not crazy to exclude 0, as otherwise the lowest common multiple of any two numbers would be 0, but it should be spelled out!

@richardelwes @peterrowlett This is getting a bit advanced, but the best way to think about the lowest common multiple is that 'lowest' is meant in the sense of the divisibility ordering. So 0 isn't the lowest common multiple of any two numbers because it is in fact the highest number!
