Beyond the definition

A factor is something that contributes to a result—like an ingredient in a recipe or a reason why something happens. Think of baking a cake: flour, sugar, and eggs are all factors that influence the final product. Or consider why a plant might not grow; a lack of sunlight could be a key factor.

The word "factor" can also refer to a specialized business agent. In finance, a factor is a person or company that buys another company's accounts receivable to give it immediate cash. It is also used in math, where a factor is a number that divides evenly into another number, like 2 and 3 in 6. So, whether it involves ingredients, causes, business agents, or numbers, a factor always plays an important part in the outcome.
