DIVISIBILITY BY Four :

Rule: lf the last two digits of a number is divisible by 4, the number is divisible by 4. The number having two or more zeros at the end is also divisible by 4.
For example :
(1) 526428 : 28 is divisible by 4, therefore, the number is divisible by 4.
(2) 5300 : There are two zeros at the end, so it is divisible by 4.
(3) 134000 : As there are more than two zeros, the number is divisible by 4.
(4) 134522 : As the last two-digit number (22) is not divisible by 4, the number is not divisible by 4.
Note: The same rule is applicable to check the divisibility by 25. That is, a number is divisible by 25 if its last two digits are either zeros or divisible by 25.
