I remember having to fumble across quite a lot in my Math class, trying to figure out if a number is a prime number or not.
But thanks to the internet et al, determining if a number is a prime number or not is just a link away.
If you want to determine, if a number is prime or not, head to Math.com Prime number calculator and enter the number you want to test, click on the Is it prime? button and you will get a instant result, pretty easy isn’t it?
Don’t know what is a prime number? A prime number are positive numbers which are not divisible by any other numbers other than itself.
