Pour chaque entier naturel n, la totalité de l'ensemble des diviseurs positifs de n devient un ensemble partiellement ordonné si nous utilisons la divisibilité comme relation d'ordre.

For every positive integer n, the set of all positive divisors of n becomes a partially ordered set if we use divisibility as the order relation.
