DIVISIBILITY OF NUMBERS BY 2 to 6

DIVISIBILITY 

BY 2

The no having 2,4,6,8,0 in its unit place is divisible by 2.

BY 3

The no whose sum of digits are divisible by 3

e.g.- 

1456 : 1+4+5+6=16 : 1+6=7
which is not divisible by 3 ,So 1456 is not divisible by 3

3957 : 3+9+5+7=24 : 2+4=6
which is not divisible by 3 ,So 3957 is not divisible by 3

BY 4

The no whose last two digits are divisible by 4 is divisible by 4.

5588 : 88 is divisible by 4
So 5588 is divisible by 4.

BY 5

The no having 0,5 in its unit place is divisible by 5.

6679 : 9 is unit digit place ,So 6679 is not divisible by 5.

BY 6

The no divisible by 2 and 3 is divisible by 6.

7896 : it is divisible by 2 because unit place is 6
and 7+8+9+6=30 : 3+0=3 divisible by 3
So 7896 is divisible by 6
