Prime Factors
Returns a vector containing the prime factors of n.
factors(n)
n |
nonnegative integer |
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.
Vector containing the prime factors of n.
