Using the divisibility rule check if 1111111 is divisible by 11?

Ans.1111111 is not divisible by 11 in any way. This is due to the fact that the difference between the sum of the digits at the odd and even positions, starting with the left-most digit, is not 0 or a number divisible by 11. The sum of the digits in odd locations is 1+1+1+1 = 4, while the sum of the digits in even places is 1+1+1+1 = 3. As a result, the difference is 4 – 3, or 1. We can say that 1111111 is not divisible by 11 because 1 is not divisible by 11.
