So there's a trick to the divisibility rules:

2- if the last digit is even, it is divisible by 2.

3- add the digits together (ex. 123 - 1 + 2 + 3). The sum must be divisible by three for the number to be divisible by 3.

4- if the last 2 digits are divisible by 4, then the number is divisible by 4.

5- if the last digit is 0 or 5, the number is divisible by 5.

6- if the number is divisible by 2 AND 3, then it is divisible by 6.

9- like three, add the digits together (ex. 123 - 1 + 2 + 3). The sum must be divisible by nine for the number to be divisible by 9.

10. The ones digit is 0.

Knowing this knowledge, we can answer the problems.

1. 5 + 6 + 7 + 3 = 21

  • 21 is divisible by 3 and 9. Therefore, 5,673 is divisible by 3 and 9.

2. 4,560-

  • It ends in 0, so it is automatically divisible by 2 and 10.

4 + 5 + 6 + 0 = 15

  • 15 is divisible by 3 but not 9.

Answer for #2: 4,560 is divisible by 2, 10, and 3.

3. 108,756

  • It ends in 6, so it is automatically divisible by 2.

1 + 0 + 8 + 7 + 5 + 6 = 27

  • 27 is divisible by 2 AND 9, so they are in too.
  • It is also divisible by 6 because 108,756 is divisible by 2 and 3.
  • It is not, however, divisible by 5 because it doesn't end in 0 or 5.

Answer to #3: 108,756 is divisible by 2, 3, 6, and 9.
