Divisibility rule of 5

Divisibility Rule of "5":

Of all the divisibility rules, Divisibility rule of 5 is very easy we can easily said at fraction of seconds

If the last digit of the number is either 5 or 0 then we can easily said that the whole number is divisible by 5

For Example:

Is the number 4356534354565345 divisible by 5?

Our answer is YES

On seeing last digit of the number i.e, 5 We simply said that the number is divisible by 5

Divisibility Rule Of the "3" and its powers

Divisibility Rule of 3:

When a number is divisible by " 3 " then the sum of the all the digits must be divisible by 3

For Example(1), 93 

            In the above number, there are two digits 9and 3

the sum of the two digits 3+9=12 and  check whether sum is divisible 3 r not Clearly, the sum 12 is divisible by 3 then 93 is divisible by 3

        (2) 123456789

                  In the above number, there are 9 digits 

the sum of all the digits  1+2+3+4+5+6+7+8+9=45

45 is divisible by 3 then the whole number is divisible by 3

For the powers of " 3 " 
3^2=9, if the sum of the digits  divisible by 9 then the whole number is divisible by 9
3^3=27, if the sum of the digits divisible by 27 then the whole number is divisible by 27
For Example:    585 
sum of the 585 is 5+8+5=18 
We know 18 is divisible by 9 then the number 585 is divisible by 9

Simple Divisibility rule for 2 and its power

In the Last class, we had seen the Divisibility of " 2"
Similarly, for different powers of  " 2 " mean non-roots words like 2^2=4, 2^3=8,-----
Divisibility rule for 2^1=2, we had checked the last digit of the number is divisible by 2 
for 2^2=4 we need to check the last 2 digits of the number must be divisible by 4 then the whole number is divisible by 4
For example,    Is 2345677808 divisible by 4
On sight, we can say that last two digits " 08" divisible by 4 
then the whole number is divisible by " 4 "
Similarly, depending on the power of the 2 we need to take the last digits to check whether the number is divisible by that number r not
If the  divisibility of 
            2^2=4, it is the second power of 2 so we need to check whether last two digits of the number are divisible 4 or not
           2^3=8,it is the third power of 2 so we need to check whether last three digits of the number are divisible by 8 or not
           2^4=16,it is a fourth power of 2 so we need to check whether last four digits of the number are divisible by 16 or not
    Similarly, for all power of the two, we need to check depending on the power and the last digits of the number
For Example,
 Is it 6348394863847634986734837568 divisible by 8
as we know that 8 is the third power of 2 
We check that last three digits of the number 568 are divisible by 8 
568/8=71, so that whole number is divisible by 8

DIVISIBILITY RULES

Divisibility Rules of the rules of the number 2,3,4,5,6,7,8,9,10,11 given below
Basically, Divisibility rules are classified into two groups 
Root numbers and Non root numbers
Root numbers know simply as prime number like 2,3,5,7,11
Other than the roots words are called Non root numbers or  non prime number
I will clearly explain this root words after the learning the divisibility rules of the Root numbers

Divisibility Rule of ''2'':

When a number is divisible by 2 then the last digit of the number must be divisible by 2

For example :   64

                In the above number last digit is "4" which is a multiple of 2 .Clearly, we can say that the above number 64 is divisible by 2

 Normal checking:  64/2=32

 The above statement is verified

            

     THE MAN WHO KNEW INFINITY

 The man who was born in an impecunious family and strive to elevate his thoughts throughout the world at the age of 24 years and a first Indian as a member of royal society  he is only person who knows the infinity he is none other than the great indian mathmathecian
                                                  """" SRINIVASA RAMANUJAN""""
        Independence day is the greatest indian freedom fight movement against the british ruling on august 15 after movement the people feel proud to born in india because of great mathmathecian birthday srinivasa ramanujan on aug16
            On this auspicious day, we need to rewind achievements the your famed person sir  SRINIVASA RAMANUJA
    
             

Happy Independence Day to all my friends

I am very glad to be an Indian and I am very delight to start my journey towards the websites on Independence Day.
