What are prime numbers? - Answers

Prime numbers are numbers that are only divisible by 1 and the number itself. Some examples of prime numbers are:1,2,3,5,7,11,13,17,19,23,27,29,31,37,41,etc.Prime numbers can go on forever; you just have to find out if its only factors are 1 and itself.Example:9 is not a Prime number because other than 1 and 9, it is also divisable by 3.13 is a Prime number because its only factors to equal 13 are 1 and 13.Even numbers, with the exception of 0 and 2, cannot be prime numbers.I'm a different person:1 isn't a prime number although many people think it is. this is because a prime number is divisible by itself and 1 but in this case it is the same number so this time 1 isn't a prime number. The definition is that a prime number is a natural number (integers 1 and greater) that has exactly two unique factors: 1 and itself. The number 1 does not have two unique factors.
