Divisibility of a number by 3 shortcut tricks are very important thing to know for your exams. Competitive exams are all about time. If you know time management then everything will be easier for you. Most of us miss this thing. We provide examples on Divisibility of a number by 3 shortcut tricks here in this page below. We try to provide all types of shortcut tricks on divisibility of a number by 3 here. We request all visitors to read all examples carefully. These examples here will help you to better understand shortcut tricks on divisibility of a number by 3.
Before doing anything we recommend you to do a math practice set. Write down
twenty math problems related to this topic on a page. Do first ten maths using basic formula of this math topic. You also need to keep track of Timing. Write down the time taken by you to solve those questions. Now practice our shortcut tricks on divisibility of a number by 3 and read examples carefully. After doing this go back to the remaining ten questions and solve those using shortcut methods. Again keep track of the time. This time you will surely see improvement in your timing. But this is not all you need. You need more practice to improve your timing more.
If the Sum or addition of all numbers that is given is divisible by 3 then the number is divisible by 3.

We are try to calculate divisibility of a number by 3 or any number using divisor 3, but if any large numbers is given we are not able to perform fast ,and using some rule and shortcut tricks we are calculate the divisibility of a numbers by 3.
Divisibility of a number by 3
If the Sum or addition of all numbers that is given is divisible by 3 then the number is divisible by 3.
Example: 861 / 3 = 287. (8+6+1) = 15 and 15 is divisible by 3, So the 861 is divisible by 3.
Example: 22104 / 3 = 7368. (2+2+1+0+4) = 9. 9 / 3 = 3, So 22104 divisible by 3.
Example: 99954 / 3 = 33318. (9+9+9+5+4) = 36. 36 / 3 = 12, So 99954 divisible by 3
Example: 87921 / 3 = 29307. (8+7+9+2+1) = 27. 27 / 3 = 9, So 87921 divisible by 3
Example: 69321 / 3 = 23107. (6+9+3+2+1) = 21. 21 / 3 = 7, So 69321 divisible by 3
Example: 1359 / 3 = 453. (1+3+5+9) = 18. 18 / 3 = 6, So 1359 divisible by 3
Note: So Before going to divisible by 3 any number, first check the addition of all numbers is divisible by 3.
