Divisor

Definition

A divisor is a number or expression that divides another number or expression without leaving a remainder. It is a fundamental concept in the operation of division, which is the inverse of multiplication.

5 Must Know Facts For Your Next Test

1. The divisor determines how many times the dividend can be subtracted from itself before reaching zero.
2. In polynomial division, the divisor is the expression being divided into the dividend, which is a polynomial.
3. The degree of the divisor must be less than or equal to the degree of the dividend for the division process to work.
4. Factoring a polynomial can be done by finding a common divisor among the terms of the polynomial.
5. The greatest common divisor (GCD) of two or more expressions is the largest expression that divides each of the expressions without a remainder.

Review Questions

• Explain the relationship between the divisor, dividend, and quotient in the context of division.
  • In the division operation, the divisor is the number or expression that is used to divide the dividend. The quotient is the result of this division, representing how many times the divisor goes into the dividend. The divisor determines how the dividend is partitioned, and the quotient represents the outcome of this partitioning process. The relationship between these three elements is fundamental to understanding division and its applications in mathematics.
• Describe the role of the divisor in the process of polynomial division.
  • In polynomial division, the divisor is the expression that is being divided into the dividend, which is a polynomial. The degree of the divisor must be less than or equal to the degree of the dividend for the division process to work. The divisor determines how the polynomial is divided, and the resulting quotient and remainder are important in understanding the structure and properties of the original polynomial. The divisor is a crucial component in the process of dividing one polynomial by another.
• Analyze the significance of the greatest common divisor (GCD) in the context of factoring polynomials.
  • The greatest common divisor (GCD) of two or more expressions is the largest expression that divides each of the expressions without a remainder. Finding the GCD of the terms in a polynomial is an important step in the process of factoring that polynomial. By identifying the GCD, you can factor out a common divisor from the polynomial, which can simplify the expression and make it easier to work with. The GCD is a fundamental concept in factoring polynomials and understanding their underlying structure.
