DIVISIBILTY RULE FOR 2
A number is divisible by 2 if it has 0,2,4,6 or 8 at its one's place.
Any number that ends with any of these five numbers is divisible by 2.
So you just need to remember these five numbers, these are divisible by 2 and all numbers ending with these numbers are divisible by 2.
DIVISIBILITY RULE FOR 3
There is a rule to find whether a number is divisible by 3 if a number is having more than one digit and for a single-digit number, we need to remember the 3,6,9 are divisible by 3.
Now for all the numbers having more than one digit there exist a very simple rule if the sum of digits is divisible by 3 the number is divisible by 3.
DIVISIBILITY RULE FOR 4
16,10,24,64,30,20,8 which are having two digits or one digit, you cannot find if they are divisible by 4 or not by any rule you need to do the actual division.
But rule exists if the number is having more than two digits.
In any number which is having more than two digits, if the number formed by the last two digits is divisible by 4 then that number is divisible by 4.
For example

116
The number formed by the last two digits is 16 and
Is 16 divisible by 4
16 divide by 4 is 4 so, 16 is divisible by 4.
So 116 is also divisible by 4.
