@RobJLow @peterrowlett I like @OscarCunningham's suggestion of interpreting "lowest" with respect to the order "x ≤ y iff x divides y"; then 0 is the *greatest* common multiple 😉 Might be a bit advanced for primary school, though.

@pozorvlak @peterrowlett @OscarCunningham Yes, ordering by divisibility is kind of neat - as you almost say, 0 is maximal. There are some fun games to play there (the non-negative numbers form a complete lattice), but maybe not in primary school.
