Factors refer to the numbers that can be multiplied together to give a specific number. In other words, they are the divisors of a number that divide it evenly. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12 because these numbers divide 12 without leaving a remainder. Factors can be found by dividing the given number by other numbers and checking if the division is exact.
