If it can not be divided by anything as a whole.
==============new answer...
The above is true, but "primeness" testing has become a major research branch of theoretical math. If I give you a large number, (eg: 123,456,789,012,345 ) can you prove it is or is not prime??
If you figure out a way, apart from attempting to divide it by all its potential factors like 2, 3, 4, 5, etc, etc. be sure to write it up and have it notarized, certificated, recorded, and then publish it. You will be the hero (or heroine) of the mathematical world. Also some of the eminent mathematical theoreticians will probably want to kill you.
The previous prime number is 23,456,787,559 and the next prime number is 23,456,787,593.
Prime factorization is when you find all the prime factors of a number.
Find a prime number that is even. 2.
It is.
The prime factors of a squared number are the prime factors, if any, of its square root.
Divide the prime number.
2 is the least prime number.
The previous prime number is 23,456,787,559 and the next prime number is 23,456,787,593.
13 is a prime number because u cant find 13 as a product on a multiplication!
to answer a prime number you must find a number that goes into it and that divides by itself :)

find the prime factorization to the number 81
It is.
The prime factors of a squared number are the prime factors, if any, of its square root.
A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
The prime factorization of 15332 • 17153 is not a prime number
