Physics of Sound homework question PLEASE!

  1. Oct 29, 2004 #1
    I cannot figure this one out...can someone help please?

    Say we are listening to two musical instruments, one of (fundamental)frequency 320 Hz and the other of frequency 270 Hz. Assume that each instrument has all possible harmonic overtones. At what frequency is partial number 5 of the combined sound?

    "Harmonic overtones" are multiples of the fundamental frequency. What frequency is the "least common multiple" of 320 and 270? What is 5 times that?
