Understanding the Concept of Greatest Common Factor (GCF)
In mathematics, the greatest common factor (GCF) of a set of numbers or expressions is the largest expression that divides each of the numbers or expressions without leaving a remainder. In the context of polynomial expressions, the GCF is the largest expression that divides each term of the polynomial without leaving a remainder.
Identifying the Greatest Common Factor of a Polynomial Expression
To identify the GCF of a polynomial expression, we need to factor out the common factors from each term. The common factors are the factors that appear in each term of the polynomial. We can use the distributive property to factor out the common factors.
Factoring Out the Greatest Common Factor
Let's consider the polynomial expression $8xy^5 - 16x2y3 + 20x4y4$. To find the GCF, we need to factor out the common factors from each term.
Step 1: Identify the Common Factors
The common factors of the polynomial expression are the factors that appear in each term. In this case, the common factors are $8xy^5$, $16x2y3$, and $20x4y4$. However, we can see that the greatest common factor is not $8xy^5$, but rather a combination of the factors.
Step 2: Factor Out the Greatest Common Factor
To factor out the greatest common factor, we need to find the largest expression that divides each term without leaving a remainder. We can start by factoring out the greatest common factor of the coefficients, which is $4$.
Step 3: Factor Out the Greatest Common Factor of the Variables
Next, we need to factor out the greatest common factor of the variables. We can see that the greatest common factor of the variables is $xy^3$.
Step 4: Combine the Factors
Now, we can combine the factors to find the greatest common factor of the polynomial expression. The greatest common factor is $4xy^3$.
Conclusion
In conclusion, the greatest common factor of the polynomial expression $8xy^5 - 16x2y3 + 20x4y4$ is $4xy^3$. This is the largest expression that divides each term of the polynomial without leaving a remainder.
Answer
The correct answer is A. $4xy^3$.
Explanation
The other options are incorrect because they do not divide each term of the polynomial without leaving a remainder. Option B, $4x4y3$, does not divide the first term $8xy^5$ without leaving a remainder. Option C, $8xy^5$, does not divide the second term $-16x2y3$ without leaving a remainder. Option D, $2xy^9$, does not divide any of the terms without leaving a remainder.
Example
Let's consider another example to illustrate the concept of greatest common factor. Suppose we have the polynomial expression $12x2y3 - 18x3y4 + 24x4y5$. To find the GCF, we need to factor out the common factors from each term.
Step 1: Identify the Common Factors
The common factors of the polynomial expression are the factors that appear in each term. In this case, the common factors are $12x2y3$, $18x3y4$, and $24x4y5$.
Step 2: Factor Out the Greatest Common Factor
To factor out the greatest common factor, we need to find the largest expression that divides each term without leaving a remainder. We can start by factoring out the greatest common factor of the coefficients, which is $6$.
Step 3: Factor Out the Greatest Common Factor of the Variables
Next, we need to factor out the greatest common factor of the variables. We can see that the greatest common factor of the variables is $x2y3$.
Step 4: Combine the Factors
Now, we can combine the factors to find the greatest common factor of the polynomial expression. The greatest common factor is $6x2y3$.
Conclusion
In conclusion, the greatest common factor of the polynomial expression $12x2y3 - 18x3y4 + 24x4y5$ is $6x2y3$. This is the largest expression that divides each term of the polynomial without leaving a remainder.
Answer
The correct answer is A. $6x2y3$.
Explanation
The other options are incorrect because they do not divide each term of the polynomial without leaving a remainder. Option B, $6x3y4$, does not divide the first term $12x2y3$ without leaving a remainder. Option C, $12x2y3$, does not divide the second term $-18x3y4$ without leaving a remainder. Option D, $2x4y5$, does not divide any of the terms without leaving a remainder.
