Introduction

In algebra, the greatest common factor (GCF) of two or more expressions is the largest expression that divides each of the given expressions without leaving a remainder. Finding the GCF of algebraic expressions is an essential skill in mathematics, particularly in solving equations and simplifying expressions. In this article, we will discuss how to find the GCF of two given expressions: $12v^5x^7$ and $30v^3x^4w^6$.

Understanding the Concept of GCF

The GCF of two or more expressions is the product of the common factors of the expressions. To find the GCF, we need to identify the common factors of the expressions and multiply them together. The common factors are the factors that appear in both expressions.

Step 1: Factorize the Expressions

To find the GCF, we need to factorize the given expressions. Factorizing an expression involves breaking it down into its prime factors.

• $12v^5x^7$ can be factorized as $2^2 \cdot 3 \cdot v^5 \cdot x^7$
• $30v^3x^4w^6$ can be factorized as $2 \cdot 3 \cdot 5 \cdot v^3 \cdot x^4 \cdot w^6$

Step 2: Identify the Common Factors

Now that we have factorized the expressions, we can identify the common factors. The common factors are the factors that appear in both expressions.

• The common factors of $12v^5x^7$ and $30v^3x^4w^6$ are $2$, $3$, and $v^3$.

Step 3: Multiply the Common Factors

To find the GCF, we need to multiply the common factors together.

• The GCF of $12v^5x^7$ and $30v^3x^4w^6$ is $2 \cdot 3 \cdot v^3 = 6v^3$.

Conclusion

In conclusion, finding the GCF of algebraic expressions involves factorizing the expressions, identifying the common factors, and multiplying the common factors together. By following these steps, we can find the GCF of any two or more expressions. In this article, we found the GCF of $12v^5x^7$ and $30v^3x^4w^6$ to be $6v^3$.
