WebHere an easy way to test for divisibility by 11. Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since … WebDivisibility Test by 11 Subtract the last digit from the remaining leading truncated number. If the result is divisible by 11 then so was the first number. Apply this rule over and over again as necessary. For example, let’s take the number 19151. 19151 → 1915 – 1 = 1914 1914 → 191 – 4 = 187 187 → 18 – 7 = 11 Hence, 19151 is divisible by 11.

Webup with our own divisibility rules. Let’s think about the rule for 13. Every number with multiple digits can be split into a “head” H and a tail “T”, where the tail is just the ones’ digit. For example, with the number 208, the head is H=20 and the tail is T=8. The rule for divisibility by 13 is to compute H+4T, which is 52 in this ...
