Using the tests for divisibility:

  • Divisible by 3:
Add the digits and if the sum is divisible by 3, so is the original number:

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

  • Divisible by 6:
Number is divisible by 2 and 3:
  • Divisible by 2:
If the number is even (last digit divisible by 2), then the whole number is divisible by 2.

684 is even so 684 is divisible by 2.

  • Divisible by 3:
Already shown above to be divisible by 3.

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

  • Divisible by 9:
Add the digits and if the sum is divisible by 9, so is the original number:

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

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

Is 684 divisble by 3?

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.


Are all numbers that are divisible by 9 also divisible by 3 are all numbers that are divisible by 3 also divisible by 9 how do you know?

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.


Are all numbers divisible by 3 also by 9 give example?

Is 32643 divisible by both 3 and 9?

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.
