Question

Without actual division show that I l is a factor of
each of the following numbers:
1111​

Answer 1

Step-by-step explanation:

1111

Sum of digits at the odd places = 1 + 1 = 2

Sum of digits at the even places = 1 + 1 = 2

So the difference between the two sums = 2 – 2 = 0

Hence, 1111 is divisible by 11 as the difference between the two sums is zero.
