 the set of positive divisors

 Calling Sequence divisors(n)

Parameters

 n - integer

Description

 • Important: The numtheory package has been deprecated.  Use the superseding command NumberTheory[Divisors] instead.
 • The function divisors will compute the set of positive divisors of its integer argument n.
 • The command with(numtheory,divisors) allows the use of the abbreviated form of this command.
