Lesson
Divisibilty Rules
| 2 | if the number ends in an even number |
| 3 | if the sum of the digits is divisible by 3 |
| 4 | if the last two digits form a number divisible by 4, the number is also. |
| 5 | if the number ends in a 5 or 0 |
| 6 | if the number is divisible by both 3 and 2, it is also divisible by 6. |
| 9 | if the sum of the digits is divisible by 9 |
| 10 | if the number ends in a 0 |
