See prime factorization algorithm for details for how to do this in practice for larger numbers.The importance of this theorem is one of the reasons for the exclusion of 1 from the set of prime numbers.
The prime number theorem says that the proportion of primes less than ''x'' is asymptotic to 1/ln ''x'' (in other words, as ''x'' gets very large, the likelihood that a number less than ''x'' is prime is inversely proportional to the number of digits in ''x'').
''Prime ideals'' are a important tool and object of study in commutative algebra, algebraic number theory and algebraic geometry.The prime ideals of the ring of integers are the ideals (0), (2), (3), (5), (7), (11),...A central problem in algebraic number theory is how a prime ideal factors when it is ''lifted'' to an extension field.

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.
For a long time, prime numbers were thought as having no possible application outside of number theory; this changed in the 1970s when the concepts of public-key cryptography were invented, in which prime numbers formed the basis of the first algorithms such as the RSA cryptosystem or the Diffie-Hellman key-exchange algorithm.
Twin prime conjecture: A twin prime is a pair of primes with difference 2, such as 11 and 13.
A probable prime is an integer which, by virtue of having passed a certain test, is considered to be probably prime.
With this definition, the primes of the field Q of rational numbers are represented by the standard absolute value function (known as the "infinite prime") as well as by the p-adic valuations on Q, for every prime number p.
Given a prime number p, we find that φ(p) + σ(p) = 2p (φ is Euler's totient function and σ is the sum of divisors function).
Accepting 1 as a prime would render Wilson's primeth sequence merely a copy of the sequence of prime numbers with 1 added at the beginning.
For a prime number p, there is no solution to the equation nq = p, where q is another prime number and n is any other positive integer; this is to say, no prime is the product of another prime and an integer.

The sum of two famous baseball records: the number of homeruns hit by Babe Ruth (714), and the number of the homerun hit by Hank Aaron to break the Babe's record (715).
The minimum prime p such that p + 1 each has exactly 4 distinct prime factors.
The largest known Smarandache-Wellin prime is the concatenation of the first 1429 prime numbers.
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.
Riemann hypothesis, which essentially says that the primes are as regularly distributed as possible.
Cube, prime numbers are used by the characters to escape from a mysterious facility.
It is also a Stern prime, a Pell number, and a Markov number, appearing in infinitely many solutions to the Markov Diophantine equation involving odd-indexed Pell numbers.
Despite being a prime, two is also a highly composite number, because it has more divisors than one.
Taking the square root of a number is such a common mathematical operation, that the spot on the root sign where the exponent would normally be written for cubic roots and other such roots, is left blank for square roots, as it is considered tacit.

There are infinitely many Mersenne prime but not Fermat primes.
