![]() Main Article: Fundamental Theorem of Arithmetic ![]() Prime numbers act as "building blocks" of numbers, and as such, it is important to understand prime numbers to understand how numbers are related to each other. ![]() Finally, prime numbers have applications in essentially all areas of mathematics. The RSA method of encryption relies upon the factorization of a number into primes. Prime numbers are also important for the study of cryptography. Nearly all theorems in number theory involve prime numbers or can be traced back to prime numbers in some way. Prime numbers are critical for the study of number theory. 1 is the only positive integer that is neither prime nor composite. All positive integers greater than 1 are either prime or composite. For example, 4 is a composite number because it has three positive divisors: 1, 2, and 4. In contrast to prime numbers, a composite number is a positive integer greater than 1 that has more than two positive divisors. ![]() For example, 5 is a prime number because it has no positive divisors other than 1 and 5. A prime number is a natural number greater than 1 that has no positive integer divisors other than 1 and itself.
