no, first Prime number is 2 NASA considers 1 a prime number, since it has no whole number factors except for itself. Check this : http://en.wikipedia.org/wiki/Prime_number 1 is not a prime number Okay, it is 2, but 1 used to be taught as the first prime number, back when Pluto was recognized as the ninth planet.

First prime number?
The first prime number is 2. If you're wondering why 1 is not prime, well, probably because you cannot break a number down if you divide it by 1. When it comes to prime factorization, if you bring 1 into it, the number you start with will stay the same (e.g., If you star a "prime factorization tree" for 100 and start off with 1, you will still have 100. You do not "grow" another "branch.")

How do you figure out what a prime number?
Well, lets first ask, What is a Prime Number? A Prime Number is a number that can only be multiplied by 1 and itself. So how do you find out what is a prime number? This is an example of a prime number:17. Try to multiply numbers and see if you get 17. You won't. 17 can only be multiplied by 1 and itself. So that's why it is a prime number. Pick a number in the future and try to multiply to it. If you don't get that number as an answer, its a prime number, if you get it as an answer, it is NOT a prime number.
