If the sum of the digits at even places subtract the sum of the digits at odd places is equal to 0 or divisible by 11, then the number is divisible by 11.For example,

Is 725364 divisible by 11?

The sum of the digits at even places:

7 + 5 + 6 = 18

The sum of the digits at odd places:

2 + 3 + 4 = 9

18 - 9 = 9 (Not divisible by 11)

Therefore, 725364 is not divisible by 11

Let's see another example:

Is 4758237 a multiple of 11?

The sum of the digits at even places:

7 + 8 + 3 = 18

The sum of the digits at odd places:

4 + 5 + 2 + 7 = 18

18 - 18 = 0

Therefore, 4758237 is a multiple of 11
