Add the digits of the number together and if the sum is divisible by 3 then the original number is divisible by 3.
The test can be applied to the sum and so the summation can be repeated until a single digit remains; if this digit is 3, 6 or 9 then the original number is divisible by 3.

Which divisibility rule can be used to show 585 is divisible by 3?
The divisibility rule of 3 is that you add the digits together and then if the number you come up with is divisible by 3, then the number itself is divisible by 3. In this instance, 5 + 8 + 5 = 18/3 = 6, therefore, 585 is divisible by 3.
What is the divisibility rule for 42?
The divisibility rule for 42 isdivisibility by 2, ANDdivisibility by 3, ANDdivisibility by 7.Divisibility by 2 requires the number to be even. That means it must end in 0, 2, 4, 6 or 8.Divisibility by 3 requires that the digital root of the number is divisible by 3. That is, the sum of the digits is divisible by 3. If the first sum is large, you can calculate the digital root of the digital root (and again, if necessary) and check that for divisibility by 3.The divisibility rule for 7 is more difficult.Take the last digit (units).From the number formed by the remaining digit, subtract twice the last digit.If the answer is divisible by 7 (including zero or negative numbers), then the original number is divisible by 7.For large numbers, repeat the process to bring the number down to a manageable size.
What is the divisibility test for 15?
It is divisibility by 3 and divisibility by 5.Divisibility by 3: the digital root of an integer is obtained by adding together all the digits in the integer, with the process repeated if required. If the final result is 3, 6 or 9, then the integer is divisible by 3.Divisibility by 5: the integer ends in 0 or 5.

Why 36940 is divisible by 12?
The number 36940 is divisible by 12 because it meets the criteria for divisibility by both 3 and 4. To check for divisibility by 3, we sum the digits (3 + 6 + 9 + 4 + 0 = 22), and since 22 is not divisible by 3, we need to reassess. However, for divisibility by 4, the last two digits (40) are divisible by 4. Since it fails the divisibility test for 3, 36940 is not divisible by 12.
