2. Langford pairing - Wikipedia

   en.wikipedia.org/wiki/Langford_pairing

   A Langford pairing for n = 4.. In combinatorial mathematics, a Langford pairing, also called a Langford sequence, is a permutation of the sequence of 2n numbers 1, 1, 2, 2, ..., n, n in which the two 1s are one unit apart, the two 2s are two units apart, and more generally the two copies of each number k are k units apart.

3. Complex conjugate root theorem - Wikipedia

   en.wikipedia.org/wiki/Complex_conjugate_root_theorem

   The non-real factors come in pairs which when multiplied give quadratic polynomials with real coefficients. Since every polynomial with complex coefficients can be factored into 1st-degree factors (that is one way of stating the fundamental theorem of algebra ), it follows that every polynomial with real coefficients can be factored into ...

4. Factorization - Wikipedia

   en.wikipedia.org/wiki/Factorization

   In mathematics, factorization (or factorisation, see English spelling differences) or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind. For example, 3 × 5 is an integer factorization of 15, and (x – 2)(x + 2) is a polynomial ...

5. Amicable numbers - Wikipedia

   en.wikipedia.org/wiki/Amicable_numbers

   However, amicable numbers where the two members have different smallest prime factors do exist: there are seven such pairs known. [8] Also, every known pair shares at least one common prime factor. It is not known whether a pair of coprime amicable numbers exists, though if any does, the product of the two must be greater than 10 65.

6. Euler's factorization method - Wikipedia

   en.wikipedia.org/wiki/Euler's_factorization_method

   Euler's factorization method is a technique for factoring a number by writing it as a sum of two squares in two different ways. For example the number can be written as + or as + and Euler's method gives the factorization =.
