  • My personal mobile number 9565804301 is a prime number.

    What is a prime number?$

    Any integer p greater than 1 is called a prime number if and only if its positive factors are 1 and the number p itself.
    In other words, the natural numbers which are completely divisible by 1 and themselves only and have no other factors, are called prime numbers. 2$ ,$ 3$ ,$ 5$ ,$ 7$ ,$ 11$ ,$ 13$ ,$ 17$ ,$ 19$ ,$ 23$ ,$ 29$ …$ $ $ $  etc. are prime numbers [or just Primes]. The numbers greater than 1, which are not prime are called Composite numbers.


    Thanks, Ganesh for the tip. He tweeted:

    His eight digit number couldn’t pass the ‘prime test’ as it had two prime factors but my ten digit number did. Exceptional luck!
