Divisible by 2: All even numbers are divisible by 2. Even numbers are numbers that end with either 2, 4, 6, 8, or 0. Divisible by 3: Add up the digits of the number. If that number is divisible by 3, then the original number is. If your sum is still a big number, continue to add the digits. Dividing by 4: If the last 2 digits together are divisible by 4. Dividing by 5: If the number ends in 5 or 0. Dividing by 6: If the number is divisible by 2 and 3. Divisible by 7: There is no specific rule. It can be done through manual division. Divisible by 8: If the last three digits are divisible by 8. If the number is divisible by 2, then by 2 again, and then by 2 again. Divisible by 9; The same as dividing by 3. Add up all the digits. If that number is divisible by 9 then it is divisible by 9. Dividing by 10: If the number ends with a 0.
