Condition for divisibility by 11
WebSum of digits at odd places = 6 + 7 + 7 = 20. And sum of digits at even places = 8 + 1 = 9. Difference = 20 - 9 = 11. Since difference is 11 which is divisible by 11, therefore 68,717 is divisible by 11. (iii) 3882. Sum of digits at odd places = 3 + 8 = 11 and, Sum of digits at even places = 8 + 2 = 10. Difference = 11 - 10 = 1. WebSep 8, 2016 · If and only if the alternating digit sum in decimal radix is divisible by 11, so is the original number. It can be used when the number you want to test divisibility for is one more than the radix of the number system. TO test for divisibility of numbers one below the radix (e.g. 9 for the decimal system) use the ordinary digit sum.
