A whole number greater than 1 that can only be divided evenly by itself and 1 (eg, 17).
There exists an infinitude of prime numbers, as demonstrated by Euclid in about 300 B.C.. The first 30 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, and 113.
The study of prime numbers is part of number theory, the branch of mathematics which encompasses the study of natural numbers. Prime numbers have been the subject of intense research, yet some fundamental questions, such as the Riemann hypothesis and the Goldbach conjecture, have been unresolved for more than a century. The problem of modelling the distribution of prime numbers is a popular subject of investigation for number theorists: when looking at individual numbers, the primes seem to be randomly distributed, but the "global" distribution of primes follows well-defined laws.

In mathematics, a prime number (or a prime) is a natural number that has exactly two (distinct) natural number divisors, which are 1 and the prime number itself. There exists an infinitude of prime numbers, as demonstrated by Euclid in about 300 B.C.. The first 30 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, and 113
Basically, a number that can only be divided by itself and 1. (Don't get me started on perfect numbers)

A prime number is one that can be didvided only by 1, and itself. The first prime number is 2, and it is the only even one. Next follow 3, 5, 7, 11, 13, 17, 19, and so on. Hope that helps.

A prime number is a number that only has the multiples one and itself. For example the number seven is a prime number because only one and seven can be multiplied to get seven. Also 3, 5, 11.... and many more.

whoever says that one isn't a prime number doesn't know what a prime number is. A prime number is a number that can only be divisible by one and itself.
For ex. 3 is a prime number becasue it is divisible by 3 and 1 and that is it.

a number that can be divided equally either by itself, i.e. 2/2, or 1.
i.e. 6 isnt a prime number because it can be divided equally by 1, 2, 3 and 6.
7 is a prime number because it can only be divided equally by 7 or 1.

I is a number that can only be divided evenly by itself - eg, 1, 3, 5, 7, 11, 13. NOT just an odd number
