# 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!

No security issues at all, for me at least. Being professional costs it.

Nice one. I never wondered what else we can do with our Mobile number! I checked my number which is not a prime… You can say you are lucky if you get a prime number mobile SIM!!!

Yes Nilesh. Not often you see a mobile number which is a prime number. I was lucky at some end.
