WebA prime number (or prime integer, often simply called a "prime" for short) is a positive integer p>1 that has no positive integer divisors other than 1 and p itself. More concisely, a prime number p is a positive integer having exactly one positive divisor other than 1, meaning it is a number that cannot be factored.

WebNumber Theory: Prime Factorization Trial Division (Brute Force) In this series we are concerned with factorizing small numbers, less than a million or so, but often much smaller. It is useful for various reasons to know whether a number is prime. A prime number, p, is a number greater than 1, with two factors only: itself and one.
