Rules Of Divisiblity (English Medium)

Rules of divisiblity:

a) for "2": If a number having 0,2,4,6,8 in its unit place then that number will divisible by "2".

Ex:  26,14,20,108,112,40232.

b) for "3": If a numbers all digits sum divisible by "3" then that number Will divisible by "3".

Ex: 36,72,105,303.

c) for "4": If a numbers last two digits number divisible by "4" then that number Will be divisible by "4".

Ex: 124,452,4236,3200.

d) for "5": If a number having "0" & "5" in its last digit then that number Will be divisible by "5".

Ex: 25,105,120,500,4020.

e) for "6": If a number divisible by "2" & "3" then that will be divisible by "6".

Ex: 12,30,480,720.

f) for "8": If a numbers last three digits number divisible by "8" then that number Will be divisible by "8".

Ex: 280,1048,20248,10324.

g) for "9": If a numbers all digits sum divisible by "9" then that number Will divisible by "9".

Ex: 27,450,1080,90702.

h) for "10": If a number having "0" in its last digit then that number Will be divisible by "10".

Ex: 10,250,1020,28340.

I) for "11": If a number digits of odd places is equal to digits of even places (or) its difference is "0" or multiple of "11" then that number will be divisible by "11".

Ex: 523281,123453,325182,45617.

*explanation of 523281; 

Here

O=odd , E=even

   5 2 3 2 8 1

   e o e o e o

Sum of odd places digits (O) =1+2+2=5

Sum of even places digits (E)=8+3+5=16

Difference of odd & even places sum of digits=16-5=11

Difference is multiple of "11" so this number will be divisible by"11".
