Using the tests for divisibility:
6 + 8 + 4 = 18 which is divisible by 3, so 684 is divisible by 3
684 is even so 684 is divisible by 2.
684 is divisible by both 2 & 3 so 684 is divisible by 6
6 + 8 + 4 = 18 which is divisible by 9, so 684 is divisible by 9
Thus 684 is divisible by all 3, 6 & 9.

234 is divisible by: 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117 and 234.
Multiples of 9 and 6 are also divisible by three, the reverse is not true. 15 is divisible by 3, but not 6 or 9. 27 is divisible by 3 and 9, but not 6. 12 is divisible by 3 and 6, but not 9. 54 is divisible by 3, 6 and 9.
To determine which number is divisible by 3, 6, and 9, we need to check if the sum of the digits of each number is divisible by 3. For 369: 3+6+9 = 18, which is divisible by 3, 6, and 9. Therefore, 369 is divisible by 3, 6, and 9. For 246: 2+4+6 = 12, which is divisible by 3 but not by 6 or 9. Therefore, 246 is divisible by 3 but not by 6 or 9. For 468: 4+6+8 = 18, which is divisible by 3, 6, and 9. Therefore, 468 is divisible by 3, 6, and 9. For 429: 4+2+9 = 15, which is divisible by 3 but not by 6 or 9. Therefore, 429 is divisible by 3 but not by 6 or 9. Therefore, the numbers 369 and 468 are divisible by 3, 6, and 9.
The GCF of 54, 60 and 78 is 6. This leaves you with 9, 10 and 13 respectively. These are not further divisible by anything in common aside from by 1.
