A divisor, in mathematics, refers to a number that is divided by another number without leaving any remainder. In other words, if you divide one number (called the dividend) by another number (called the divisor), and the division is exact with no remainder, then the second number is called a divisor of the first number.

For example, if we consider the number 12, its divisors are 1, 2, 3, 4, 6, and 12 because when we divide 12 by each of these numbers, we get a whole number result without any remainder. On the other hand, numbers like 5, 7, or 11 are not divisors of 12 because when we divide 12 by these numbers, we do not get a whole number result.

To check if a number is a divisor of another number, you can perform the division calculation and check if the remainder is zero. If the remainder is zero, then the second number is a divisor of the first number. If the remainder is not zero, then the second number is not a divisor of the first number.
