Factorization is the process of expressing a mathematical object as a product of other mathematical objects, called factors. This concept is most commonly applied to integers, where factorization involves finding integers that multiply together to give the original integer. For example, the integer 12 can be factorized into 2 * 6 or 3 * 4. The prime factorization of 12 is 2 * 2 * 3, where each factor is a prime number. Prime factorization is unique for every integer greater than 1, according to the Fundamental Theorem of Arithmetic.

Factorization extends beyond integers to other mathematical structures like polynomials. In algebra, polynomial factorization involves expressing a polynomial as a product of simpler polynomials, often of lower degree. For instance, the polynomial x^2 - 4 can be factorized into (x - 2)(x + 2). This process is crucial for solving polynomial equations, simplifying expressions, and understanding the roots of polynomials.

The methods for factorization vary depending on the object being factorized. For integers, trial division and more advanced algorithms like the sieve of Eratosthenes or Pollard's rho algorithm are used. For polynomials, techniques include factoring by grouping, using special product formulas (like the difference of squares), and employing polynomial long division or synthetic division to find roots. Factorization is a fundamental tool in number theory, abstract algebra, and various branches of applied mathematics and computer science.
