Divisibility rule for all numbers
The rules given below transform a given number into a generally smaller number, while preserving divisibility by the divisor of interest. Therefore, unless otherwise noted, the resulting number should be evaluated for divisibility by the same divisor. In some cases the process can be iterated until the divisibility is obvious; for others (such as examining the last n digits) the result must be examined by other means. WebOr use the "3" rule: 7+2+3=12, and 12 ÷ 3 = 4 exactly Yes. Note: Zero is divisible by any number (except by itself), so gets a "yes" to all these tests. There are lots more! Not …
