Dear Sir(s),
Please, find a write-up, attached herewith, on various aspects of divisibility
Rules for prime numbers, in particular.
I have tried to deal with the different possibilities to find out whether a given number
consisting of 5 digits or more is prime or composite.
Now, I believe that a new path is opened to work on the greater prime numbers.
Thanks. Shyamal Kumar Das. 09.11.2012
