Returns a vector containing the prime factors of n.

Usage

factors(n)

Arguments

n

nonnegative integer

Value

Vector containing the prime factors of n.

Details

Computes the prime factors of n in ascending order,
each one as often as its multiplicity requires, such that
n == prod(factors(n)).

The corresponding Matlab function is called `factor', but because
factors have a special meaning in R and the factor() function in R
could not (or should not) be shadowed, the number theoretic function
has been renamed here.
