      Rules of Divisibility 1. Divisible by 2 - If last digit of any number is 0,2,4,6,8 that number will be divisible by 2 . 2. Divisible by 3 - If sum of digits of any number be divisible by 3 , that number will be divisible by 3. Ex. - 657 6+5+7 = 18  Here 18 is divisible by 3 , so 657 will be divisible by 3 . 3. Divisible by 4 - If last two digits of any number be divisible by 4 , that number will be divisible by 4 . Ex. - 571136. Here 36 is divisible by 4 , so 571136 will be divisible by 4. 4. Divisible by 5 - If last digit of any number be 0 or 5 that number will be divisible by 5. Ex. - 7320, 97565. Here last digit of 7320 is 0 and last digit of 97565 is 5 , so both numbers will be divisible by 5. 5. Divisible by 6 - If any number be divisible by 2 & 3 both , that number will be divisible by 6. Ex. - 54324 . Here last digit of the number is 4 ,so it will be divisible by 2. The sum of 5+4+3+2+4 =18 , which is divisible by 3. So this number will be divisible...
