What does factoring mean?
Factoring refers most prominently to two distinct practices that share a common root idea: reducing something to its constituent elements. In mathematics, factoring is the process of expressing a number or algebraic expression as a product of simpler components — for example, writing 12 as 2 × 2 × 3, or rewriting a quadratic equation as a product of two binomials. It is a foundational technique in arithmetic and algebra, essential for simplifying expressions and solving equations. In finance and commerce, factoring describes the sale of a company's outstanding invoices to a third party, known as a factor, which advances cash at a discount and then collects the debts directly. This gives businesses immediate liquidity rather than waiting weeks or months for customers to pay. More generally, the verb "to factor" extends to everyday reasoning, as in "factoring in the weather" when planning a trip. Whether applied to numbers, invoices, or decisions, factoring conveys the practical act of breaking a whole into workable parts.

Before banks would lend quickly enough for growing businesses, 'factors' were buying companies' unpaid invoices for centuries — making factoring one of finance's oldest cash-flow tricks.

Etymology of factoring
Both senses of factoring descend from the Latin noun "factor", meaning "one who does or makes", formed from the past participle of "facere" (to do or make). In medieval and early modern commerce, a factor was an agent who sold goods on behalf of others, and the practice of selling receivables to such agents came to be called factoring. The mathematical sense arose later, applying the same notion of breaking a quantity into multiplicative components, and the word entered English usage through these commercial and scholarly channels.
