Understanding the Concept of Greatest Common Factor (GCF)

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. In the context of algebraic expressions, the GCF is the expression that is common to both expressions and has the highest degree in each variable.

Identifying the Greatest Common Factor of the Given Terms

To find the GCF of the terms $$36x^2y4$$ and $$24xy^7$$, we need to identify the common factors in both expressions. The first step is to factorize each term into its prime factors.

Prime Factorization of the Terms

$36x^2y^4 = 2^2 \cdot 3^2 \cdot x^2 \cdot y^4$
$24xy^7 = 2^3 \cdot 3 \cdot x \cdot y^7$

Identifying the Common Factors

The common factors between the two expressions are $$2^2$$, $$3$$, and $$x$$, and $$y^4$$. We can now multiply these common factors to find the GCF.

Calculating the Greatest Common Factor

GCF = 2^2 \cdot 3 \cdot x \cdot y^4 = 12xy^4

Evaluating the Answer Choices

Now that we have found the GCF, we can evaluate the answer choices to determine which one is correct.

Answer Choice 1: $$12xy^4$$

This is the GCF we calculated earlier, so it is the correct answer.

Answer Choice 2: $$24x^2y7$$

This expression is not the GCF of the two terms. It has a higher degree in $$x$$ and $$y$$ than the GCF we calculated.

Answer Choice 3: $$6x^2y3$$

This expression is not the GCF of the two terms. It has a lower degree in $$x$$ and $$y$$ than the GCF we calculated.

Answer Choice 4: $$3xy$$

This expression is not the GCF of the two terms. It has a lower degree in $$x$$ and $$y$$ than the GCF we calculated.

Conclusion

The greatest common factor of the terms $$36x^2y4$$ and $$24xy^7$$ is $$12xy^4$$. This is the expression that is common to both terms and has the highest degree in each variable.
