__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".*
