In mathematics, the Greatest Common Factor (GCF) of two or more numbers is the largest positive integer that divides each of the numbers without leaving a remainder. However, when dealing with algebraic expressions, the concept of GCF becomes more complex. In this article, we will explore the GCF of two algebraic expressions, specifically the GCF of $$44 j^5 k^4$$ and $$121 j^2 k^6$$.

Understanding the Basics of GCF

Before we dive into the problem, let's review the basics of GCF. The GCF of two numbers is the largest number that divides both numbers without leaving a remainder. For example, the GCF of 12 and 18 is 6, because 6 is the largest number that divides both 12 and 18 without leaving a remainder.

The GCF of Algebraic Expressions

When dealing with algebraic expressions, the GCF is the product of the common factors of the variables and the common factors of the coefficients. In other words, the GCF of two algebraic expressions is the expression that results from multiplying the common factors of the variables and the common factors of the coefficients.

Finding the GCF of $$44 j^5 k^4$$ and $$121 j^2 k^6$$

To find the GCF of $$44 j^5 k^4$$ and $$121 j^2 k^6$$, we need to identify the common factors of the variables and the common factors of the coefficients.

The common factors of the variables are $$j^2$$ and $$k^4$$.
The common factors of the coefficients are 1, because the coefficients are 44 and 121, and there is no common factor other than 1.

Calculating the GCF

Now that we have identified the common factors of the variables and the coefficients, we can calculate the GCF by multiplying the common factors of the variables and the common factors of the coefficients.

GCF = $$j^2 \cdot k^4$$

However, we need to consider the coefficients as well. The coefficients are 44 and 121, and the common factor of the coefficients is 1. Therefore, the GCF is:

GCF = $$1 \cdot j^2 \cdot k^4$$

Simplifying the expression, we get:

GCF = $$j^2 k^4$$

Conclusion

In conclusion, the GCF of $$44 j^5 k^4$$ and $$121 j^2 k^6$$ is $$j^2 k^4$$. This is because the common factors of the variables are $$j^2$$ and $$k^4$$, and the common factor of the coefficients is 1.

Answer

The correct answer is:

B. $$4 j^2 k^4$$

However, this is not the correct answer. The correct answer is:

B. $$4 j^2 k^4$$ is not the correct answer, but $$j^2 k^4$$ is the correct answer.

Why is the answer not among the options?

The answer $$j^2 k^4$$ is not among the options because the options are in the form of $$4 j^2 k^4$$ and $$11 j^2 k^4$$. However, the correct answer is $$j^2 k^4$$, not $$4 j^2 k^4$$ or $$11 j^2 k^4$$.

A: The common factors of the coefficients are the numbers that appear in both algebraic expressions. For example, if the two algebraic expressions are $$2x^2y3$$ and $$3x^2y4$$, the common factors of the coefficients are 1, because the coefficients are 2 and 3, and there is no common factor other than 1.

Q: How do I multiply the common factors of the variables and the common factors of the coefficients?

A: To multiply the common factors of the variables and the common factors of the coefficients, you simply multiply the variables and the coefficients together. For example, if the common factors of the variables are $$x^2$$ and $$y^3$$, and the common factors of the coefficients are 1, the GCF is $$x^2y3$$.

Q: What if the common factors of the coefficients are not 1?
