To answer this question for the third time in the past two days:
A prime number is a positive integer whose only distinct integral factors are 1 and itself. For example, 5 is a prime number because there are no other integers that divide evenly into 5 other than 1 and 5. 9 is not a prime number, since it is divisible by 3 in addition to 1 and 9. If we can ONLY write a number as itself times one, and the product of no other numbers, then it's prime.
There are an infinite amount of prime numbers, starting with 2, 3, 5, 7, 11, 13, 17, 23, 29, and so on.
Note that "1" is NOT A PRIME number. This is because it only has one unique factor: 1. If we didn't have the uniqueness restriction, then no numbers would be prime because we could write it as itself times however many ones we want. For example, 13 = 13 x 1 x 1 x1, but it's still a prime number because it only has two unique factors.

A prime is a natural number that has exactly two (distinct) natural number divisors, which are 1 and the prime itself. The first couple of prime numbers are 2, 3, 5, 7, 11, etc.
1 is not a prime number! Defining a prime as a number that is only divisible by one and itself, one is a prime. However, for purposes of factorization and some other maths stuff it is not considered a prime number.
2 is the only even prime, because any even natural number greater than 2 is a multiple of 2.
The biggest known prime has about 10.000.000 digits.

A prime number is a positive whole number that cannot be divided by another, smaller, whole number (except 1) without leaving a remainder. 0 and 1 are not considered to be primes. 2 is prime; 3 is prime; 4 is not prime because it can be divided by 2.

Prime numbers are numbers that can only be divisible by 1 and themselves, without a remainder or fraction. Some examples are 2,3,5,7,13......you get the idea...I hope.Good Luck!
