Factorize: Prime Factorization of Integers

Description

Compute the prime factorization(s) of integer(s) n.

Usage

Factorize(n)

Arguments

n
vector of integers to factorize.

Value

  • A named list of the same length as n, each element a 2-column matrix with column "p" the prime factors and column~"m" their respective exponents (or multiplities), i.e., for a prime number n, the resulting matrix is cbind(p = n, m = 1).

Details

works via Primes, currently in a cheap way, sub-optimal for large composite $n$.

See Also

Primes. For factorization of moderately or really large numbers, see the gmp package, and its factorize().
