3, 9, and 27 are the shared factors The shared composite factors will have the same prime factors. You just need to find the common prime factors and then the composites of those are the composite factors. Found this by looking at the prime factors first of 486: 2*3*3*3*3*3 Then of 216297 3*3*3*8011 I'm not sure if 8011 is prime, but it doesn't really matter - the remaining prime factors of 486 (2, 3, 3) don't go in to it. The common prime factors are 3, 3, 3 so the shared composites are the various multiples, in this case, 3,9, and 27.
