printfactors(vector(n1 [n2, ...,]), integers n1 > 0, n2 > 0, ...

Keywords: prime factors

printfactors(vector(n), where n > 0 is an integer prints n and its prime
factors, if any.  It does not return any values.

printfactors(N), where N = vector(n1,n2,...), integers n1 > 0, n2 > 0,
..., prints each element of N together with its prime factors, if any.

Example:
  Cmd> printfactors(2^2^run(5) + 1)
