The factor(6) man page says:

     -h    If the -h flag is specified, factors will be printed in "human-
           readable" format.  If a factor x divides a value n (>1) times, it
           will appear as x^n.

but that doesn't actually work for factors greater than 65537:

  $ /usr/games/factor -h 4295098369
  4295098369: 65537^2
  $ /usr/games/factor -h 4295360521
  4295360521: 65539 65539


See above.
