Is 21 divisible by 2 3 or 5?
21 is not divisible by 2 nor 5, but it is divisible by 3. To be divisible by 2 the last digit must be even (one of {0, 2, 4, 6, 8}; the last digit 1 is not one of these, thus 21 is not divisible by 2 To be divisible by 3 sum the digits and if this total is divisible by 3, then so is the original number; the test can be repeated on the sum, so by repeatedly summing the digits of the totals until a single digit remains only if that single digit is 3, 6 or 9 is the original number divisible by 3. 21 → 2 + 1 = 3 which is divisible by 3 so 21 is divisible by 3. To be divisible by 5, the last digit must be 0 or 5. The last digit of 21 is 1 which is not 0 nor 5, thus 21 is not divisible by 5.

Is 9 divisible by 1239?
No. 9 is less than 1239 so it cannot be divisible by it. Nor is 1239 divisible by 9. To test if a number is divisible by 9 add the digits and if this sum is divisible by 9 then so is the original number. As the test can be applied to the sum, repeating the summing until a single digits remains means the original number is divisible by 9 only if this single digit (also called the digital root of the number) is 9. (if it is not 9, it gives the remainder when the original number is divided by 9). For 1239: 1 + 2 + 3 + 9 = 15 → 1 + 5 = 6 which is not 9, so 1239 is not divisible by 9 (it has a remainder of 6 when divided by 9).
