About "Divisibility by 4"
Divisibility by 4 :
Here we are going to see how to how to check whether the given number is divisible by 4 or not.
If the last two digits of the given number are zeroes or the last 2 digits are divisible by 4, we can say the given number is divisible by 4.
Example 1 :
Test whether 328 is divisible by 4?
Solution :
Since the last two digits are not zeroes, we have to check whether the last two digits are divisible 4.
|
The last two two digits of the given number 328 is 28. Let us check whether it is divisible by 4 or not. |
 |
Since 28 is divisible by 4, the given number 328 is divisible by 4.
Example 2 :
Test whether 1688 is divisible by 4?
Solution :
Since the last two digits are not zeroes, we have to check whether the last two digits are divisible 4.
|
The last two two digits of the given number 1688 is 88. Let us check whether it is divisible by 4 or not. |
 |
Since 88 is divisible by 4, the given number 1688 is divisible by 4.
Example 3:
Test whether 100 is divisible by 4?
Solution :
First we have to check whether the given number 100 is divisible by 4 or not.
Since the last two digits of the given number is 00, the given number is divisible by 4.
Example 4 :
Test whether 274 is divisible by 4?
Solution :
First, we have to check whether the given number 274 is divisible by 4 or not.
The last two digits of the given number is 74. It is not divisible by 4.
Hence, we can decide 274 is not divisible by 4.
