divisors(n)

Arguments

n

integer whose divisors will be generated.

Details

The list of all divisors of an integer n will be calculated and returned in ascending order, including 1 and the number itself. For n>=1000 the list of prime factors of n will be used, for smaller n a total search is applied.

Value

Returns a vector integers.
