How can we find out the divisibility by 11?
Method 2 of 2: Using Pairs of Digits Write down your number. For example, let’s check whether 17952 is divisible by 11. Divide the digits in pairs from right to left. Draw a vertical line to separate the two rightmost digits from the rest of the number. Add the numbers together. Treat each separate section as its own number. Check whether the answer is divisible by 11.
