Best Answer

Using the tests for divisibility:

- Divisible by 3:

6 + 8 + 4 = 18 which is divisible by 3, so 684 is divisible by 3

- Divisible by 6:

- Divisible by 2:

684 is even so 684 is divisible by 2.

- Divisible by 3:

684 is divisible by both 2 & 3 so 684 is divisible by 6

- Divisible by 9:

6 + 8 + 4 = 18 which is divisible by 9, so 684 is divisible by 9

Thus 684 is divisible by all 3, 6 & 9.

Yes, 684 ÷ 9 = 76

Because 684 = 9*76

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.

72,344 is not evenly divisible by 3 or by 6 or by 9.

No, 9 is divisible by 3 and 9, but not six 3 x 9 = 27, also not divisible by 6

Sum of digits is divisible by three so yes. You can check if a number is divisible by 3 (without actually doing the division), by adding up the digits. If that sum is divisible by 3 then the original number is divisible by 3: 6 + 8 + 4 = 18 (which is divisible by 3; if not sure add again: 1 + 8 = 9, yes) You'll have to 'memorize' that 3, 6 & 9 are divisible by 3.

All numbers divisible by 9 are divisible by 3; since 9 = 3 x 3 all multiples of 9 are also multiples of 3. However, all numbers divisible by 3 are not divisible by 9, eg 6 = 2 x 3 but 6 is not divisible by 9 (since 6 is not a multiple of 9) - it only takes one counter example to disprove a theory.

All numbers divisible by 3 are NOT divisible by 9. As an example, 6, which is divisible by 3, is not divisible by 9. However, all numbers divisible by 9 are also divisible by 3 because 9 is divisible by 3.

42 is divisible by 2, 3 and 6 but not by 9.

1350 is divisible by all of the numbers of 3, 6 and 9

Because 9 is divisible by 3, this is like the rule where if a number is divisible by 2 and 3 it is also divisible by 6.

No, because when something is divisible by 6, it is divisible by 2 or 3. This is divisible by 3, but not 2.

No. For example, 9 is divisible by 3 and 9, but not 6. Even numbers that are divisble by 3 and 9 are also divisble by 6.

No. 1+9+6=16, which is not divisible by 3; 1+4+6=11, which isn't divisible by 3 either. No. 1+9+6=16, which is not divisible by 3; 1+4+6=11, which isn't divisible by 3 either.

The smallest number divisible by 3 6 and 9 is 18.

It is divisible by 2, 3, 4, 6 and 9.

not divisible by 9.but it is divisible by 4.

1, 2, 7, 3 and 6 are not divisible by 4 and/or 9. 12736 is divisible by 4 but not by 9.

9 is greater than 6 and divisible by 3.

1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

To check for divisibility by 9 sum the digits of the number and if this sum is divisible by 9 then so is the original number. For 32643: 3 + 2 + 6 + 4 + 3 = 18 which is divisible by 9 so 32643 is divisible by 9. As 9 = 3 × 3, any number divisible by 9 is also divisible by 3, thus as 32643 is divisible by 9 it is also divisible by 3. However, for completeness: to check for divisibility by 3 sum the digits of the number and if this sum is divisible by 3 then so is the original number. For 32643: 3 + 2 + 6 + 4 + 3 = 18 which is divisible by 3 so 32643 is divisible by 3.
