How to create a divisibility test

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.

WebA divisibility rule is a heuristic for determining whether a positive integer can be evenly divided by another (i.e. there is no remainder left over). For example, determining if a number is even is as simple as checking to see if its last digit is 2, 4, 6, 8 or 0. Multiple divisibility rules applied to the same number in this way can help quickly determine its prime …
