» For the second operand of a division, see division (mathematics).:For divisors in algebraic geometry, see divisor (algebraic geometry). In mathematics, a divisor of an integer n, also called a factor of n, is an integer which evenly divides n without leaving a remainder. Explanation For example, 7 is a divisor of 42 because 42/7 = 6. We also say 42 is divisible by 7 or 42 is a multiple of 7 or 7 divides 42 or 7 is a factor of 42 and we usually write 7 | 42. For example, the positive divisors… (More on Divisibility)
