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
