Divider, also called factor, refers to the situation that the quotient obtained by dividing integer A by integer b(b≠0) is an integer with no remainder. The detailed explanation is as follows:

1, the divisor of an integer is finite and can be a common divisor in some cases. For example, if a number C is both a factor of number A and a factor of number B, then C is called the common factor of A and B. The greatest common factor of all numbers is called the greatest common factor of these two numbers.

2. The concept of divisor is widely used in mathematics. For example, when decomposing prime factors, we need to find all the divisors of a given integer and multiply them to get the simplest form of the integer. In addition, divisor can also be used to solve some practical problems, such as calculating the greatest common divisor and the least common multiple.

3. Divider is an important knowledge in mathematics, which involves the divisible relationship between integers, its properties and applications. By learning divisor, we can better understand many basic concepts and principles in mathematics, thus laying a solid foundation for solving more complicated problems.
