Factoring Polynomials Using the Greatest Common Factor (GCF)

In algebra, factoring polynomials is a crucial skill that helps us simplify complex expressions and solve equations. One of the most important techniques for factoring polynomials is the Greatest Common Factor (GCF) method. In this article, we will explore how to find the GCF of two polynomials and use it to factor them.

What is the Greatest Common Factor (GCF)?

The GCF of two numbers or expressions is the largest number or expression that divides both of them without leaving a remainder. In other words, it is the product of the common factors of the two numbers or expressions.

Step 1: Find the GCF of 44 and 121

To find the GCF of 44 and 121, we need to list all the factors of each number and find the largest common factor.

• Factors of 44: 1, 2, 4, 11, 22, 44
• Factors of 121: 1, 11, 121

The largest common factor of 44 and 121 is 11.

Step 2: Find the GCF of $j^5$ and $j^2$

To find the GCF of $j^5$ and $j^2$, we need to identify the common factors of the two expressions.

• Factors of $j^5$: $j, j^2, j^3, j^4, j^5$
• Factors of $j^2$: $j, j^2$

The largest common factor of $j^5$ and $j^2$ is $j^2$.

Step 3: Find the GCF of $k^4$ and $k^6$

To find the GCF of $k^4$ and $k^6$, we need to identify the common factors of the two expressions.

• Factors of $k^4$: $k, k^2, k^3, k^4$
• Factors of $k^6$: $k, k^2, k^3, k^4, k^5, k^6$

The largest common factor of $k^4$ and $k^6$ is $k^4$.

Finding the GCF of the Polynomials

Now that we have found the GCF of each pair of factors, we can find the GCF of the two polynomials.

• GCF of 44 and 121: 11
• GCF of $j^5$ and $j^2$: $j^2$
• GCF of $k^4$ and $k^6$: $k^4$

The GCF of the two polynomials is the product of the GCFs of each pair of factors.

• GCF of $44j^5k^4$ and $121j^2k^6$: $11 \cdot j^2 \cdot k^4$

Therefore, the GCF of $44j^5k^4$ and $121j^2k^6$ is $11j^2k^4$.
