Definition of Factors
Factors are numbers that divide another number without leaving a remainder. In simpler terms, if you can divide a number 'n' by a number 'f' and get a whole number as a result, then 'f' is a factor of 'n'. For example, in the case of 40, if you divide it by 1, 2, 4, 5, 8, 10, 20, or 40, you will get a whole number. Understanding this concept is fundamental in various areas of mathematics.
