Loch's theorem, in the context of mathematics, particularly in number theory, provides a result concerning the divisibility of certain numbers by others. Specifically, it states that if \\( p \\) is a prime number and \\( a \\) is an integer not divisible by \\( p \\), then the order of \\( a \\) modulo \\( p \\) divides \\( p-1 \\).
