You have the following numbrs:

897

12,000

8190

327

In order to determine if the previous numbers are divisibles for numbers between 2 and 10, you take into account the following points:

- If last two digits are divisible by a number, and the part of the number without the last units is divisible too, you can consider that the complete number is divisible too.

- If the last digit is 0, then the number is divisible by 2 and 5 and 10.

- If the number is even, it is dividible by 2.

- In case a number ends in varios zeros you can consider if the digits before the zeros are divisible by a specific number.

- 897 is divisible by 3, because 97 is divisible by 3 and 800 too.

- 12,000 is divisible by 2, 3, 4, 5, 6, 8 and 10, because it is an even number, ends in 0 and the first digits are divisible by 3, 4, 6.

- 8190 is divisible by 2, 3, 5, 6, and 10, becaues it is even, ends in 0 and the number of last two digits is divisible by 3 and 6 and 8100 too.

- 327 is divisible by 3, because number of last two digits is divisible by 3 and 300 too.
