Characteristics of numbers divisible by 11

Characteristics of numbers divisible by 11

Add a number from the right to the left, and then calculate the difference between the odd and even digits. If the difference is a multiple of 11 (including 0), then the original number must be divisible by 11
For example, judge whether 491678 can be divided by 11
- → sum of odd digits 9 + 6 + 8 = 23
- → sum of even digits 4 + 1 + 7 = 12 23-12 = 11
Therefore, 491678 can be divided by 11
This method is called odd even difference method
