What is the Divisibility Rule of 3?
As per the Divisibility Rule of 3, a number is completely divisible if the sum of the digits in it is divisible by 3 or a multiple of 3. For example, let us take 324
Sum of digits = 3+2+4 = 9
9/3 = 3
Therefore, 324 is divisible by 3.
How do you Calculate Divisibility by 3?
Go through the simple condition over here to know about the Divisibility Rule of 3.
- The first and foremost step is to identify the given number.
- Then, find the sum of digits of the given number.
- If the sum of digits is a multiple of 3 then the given number is completely divisible by 3.
Solved Examples of Testing Divisibility by 3
To help you better understand the Divisibility Rule of 3 we have provided some solved examples below.
Example 1:
Check whether 428 is divisible by 3 or not.
Solution:
Given number is 428
We know as per the divisibility rule of 3, that a number is divisible only if the sum of digits is divisible by 3 or a multiple of 3.
Sum of digits = 4+2+8 = 14
Now dividing 14÷3 we have the remainder of 2.
As 14 is not completely divisible by 3 we can say that 428 is not divisible by 3.
Example 2.
Check if 516 is divisible by 3.
Solution:
Given number is 516
From the divisibility test of 3, we know if the sum of digits is divisible by 3 or a multiple of 3 then the given number is divisible by 3.
Sum of digits = 5+1+6 = 12
As 12 is a multiple of 3 we can say that the given number 516 is divisible by 3.
