How can write a program in scheme to find factors of a list of numbers

Question

This is the code for a single integer, how can it extends to list of function?

(define (factors n)
      (define (*factors d)
        (cond ((> d n) (list))
           


        

Answer 1

You can use for-each to iterate over a list.

(define (factors n)
  (define (*factors d)
    (cond ((> d n) (list))
          ((= (modulo n d) 0) (cons d (*factors (+ d 1))))
          (else (*factors (+ d 1)))))
  (*factors 1))

(define arbitarily-large-input (list 10 11 12))

(for-each (lambda (x)
            (display x)
            (newline))
          (map factors arbitarily-large-input))
