In mathematics, a factor is a number that divides another number evenly, without leaving a remainder. For example, in the number 12, the factors are 1, 2, 3, 4, 6, 12 because each of these numbers can multiply with another factor to produce 12. Factors are important in various mathematical operations, including simplifying fractions and finding the greatest common divisor. In a broader context, factors can refer to elements that contribute to a particular outcome or situation. For instance, in health, factors such as diet, exercise, and genetics can influence a person's well-being. Understanding these factors helps in making informed decisions and improving various aspects of life.
