WebRepeat the process for larger numbers. Example: 357 (Double the 7 to get 14. Subtract 14 from 35 to get 21 which is divisible by 7 and we can now say that 357 is divisible by 7. … WebDivisibility Test for 2: The last digit is 0, 2, 4, 6, or 8. Divisibility Test for 3: The sum of the digits is divisible by 3. Divisibility Test for 5: The last digit is 0 or 5. Divisibility Test for … A divisibility rule is a shorthand and useful way of determining whether a given integer is divisible by a fixed divisor without performing the division, usually by examining its digits. Although there are divisibility tests for numbers in any radix, or base, and they are all different, this article presents rules and … See more 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 … See more Divisibility by 2 First, take any number (for this example it will be 376) and note the last digit in the number, discarding … See more To test for divisibility by D, where D ends in 1, 3, 7, or 9, the following method can be used.
