To find multiples of 11, multiply any whole number by 11. The easiest way to do this is to multiply the number by 10, by writing a zero digit on the end and then adding 1 more lot of the number. For example, the 14th multiple of 11 is 154 because 140 + 14 = 154.
Which is not divisible by 11?
Then, we know only 0 and multiples of 11 as 11, 22, 33 and so on will be divisible by 11. Now, we can clearly see only the number 888888 gives the number as 0 which is divisible by 11 and all other numbers are not divisible by 11.
What is the remainder when is divided by 11?
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.
