  2. Euclid's theorem - Wikipedia

    en.wikipedia.org/wiki/Euclid's_theorem

    Euclid's theorem is a fundamental statement in number theory that asserts that there are infinitely many prime numbers. It was first proven by Euclid in his work Elements . There are several proofs of the theorem.

  3. Euclid–Euler theorem - Wikipedia

    en.wikipedia.org/wiki/Euclid–Euler_theorem

    The Euclid–Euler theorem states that an even natural number is perfect if and only if it has the form 2 p−1 M p, where M p is a Mersenne prime. [1] The perfect number 6 comes from p = 2 in this way, as 2 2−1 M 2 = 2 × 3 = 6, and the Mersenne prime 7 corresponds in the same way to the perfect number 28.

  4. Euclid's lemma - Wikipedia

    en.wikipedia.org/wiki/Euclid's_lemma

    Theorem — If is a prime number that divides the product and does not divide , then it divides . Euclid's lemma can be generalized as follows from prime numbers to any integers. Theorem — If an integer n divides the product ab of two integers, and is coprime with a , then n divides b .

  5. Euclid number - Wikipedia

    en.wikipedia.org/wiki/Euclid_number

    In mathematics, Euclid numbers are integers of the form E n = p n # + 1, where p n # is the nth primorial, i.e. the product of the first n prime numbers. They are named after the ancient Greek mathematician Euclid , in connection with Euclid's theorem that there are infinitely many prime numbers.

  6. List of prime numbers - Wikipedia

    en.wikipedia.org/wiki/List_of_prime_numbers

    A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem , there are an infinite number of prime numbers. Subsets of the prime numbers may be generated with various formulas for primes .

    The fundamental theorem can be derived from Book VII, propositions 30, 31 and 32, and Book IX, proposition 14 of Euclid's Elements.. If two numbers by multiplying one another make some number, and any prime number measure the product, it will also measure one of the original numbers.
