**How do you know if a number is divisible by 9?**

6 : If the number is divisible by both 3 and 2, it is also divisible by 6. 7 : Take the last digit, double it, and subtract it from the rest of the number; if the answer is divisible by 7 (including 0), then the number …... so its remainder when divided by 11 is just 2(-1)+7(1)+2(-1)+8(1), the alternating sum of the digits. (It's sum is the negative of what we found above because the alternation here begins with a -1.) But either way, if this alternating sum is divisible by 11, then so is the original number.

To test a number without doing the division: Add the digits of the number together and if this sum is divisible by 9 then so is the original number. The sum can be tested in the same way, so repeatedly add the digits of the sum until until a single digit remain. If this digit is 9 then the original number is divisible by 9; otherwise it gives the remainder when the original number is divided... CONNECT: Divisibility. If a number can be exactly divided by a second number, with no remainder, then we say that the first number is by the second number. For divisible example, 6 can be divided by 3 so we say that 6 is divisible by 3. (We can also say that 3 is a factor of 6 and 6 is a multiple of 3, but that is not what this handout is about!) It can be difficult to divide numbers which

## How To Tell If A Number Is Divisible Without Remainder

leave the same remainder upon division by d; in particular, a is divisible by d if and only if s is divisible by d . Below are the values of d (2 • d • 102) for which the alternating sum

- A remainder can never be larger than the number you are dividing by (divisor). Even if you are dividing a number by fifty-one (51), you can't have a remainder greater than or equal to fifty-one. It doesn't matter what number you use.
- If a number can be divisible by 2 without a remainder, then by definition the number is even. If the number is divided by 2 that equation yields a remainder, then the number must be odd. To put this concept into Python terms, see the code snippet below:
- 19/10/2006 · To determine whether or not a number can be evenly divided into a second number all you have to do is divide the numbers and see if the answer includes a remainder. For example, 25 cannot be evenly divided by 6: if you take 6 into 25, you’ll end up with 4 and a remainder of 1 (6 x 4 = 24; 24 + 1 = 25). By contrast, 25
