Introduction

In algebra, finding the greatest common factor (GCF) of two or more expressions is an essential skill that helps us simplify complex expressions and solve equations. The GCF of two or more expressions is the largest expression that divides each of the given expressions without leaving a remainder. In this article, we will learn how to find the GCF of two algebraic expressions: $18u^3x^7y^5$ and $30u^4x^6$.

Understanding the Concept of GCF

---

Before we dive into finding the GCF of the given expressions, let's understand the concept of GCF. The GCF of two or more numbers is the largest number that divides each of the given 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.

Similarly, in algebra, the GCF of two or more expressions is the largest expression that divides each of the given expressions without leaving a remainder. To find the GCF of two expressions, we need to identify the common factors of the two expressions and multiply them together.

Step 1: Identify the Common Factors

---

To find the GCF of $18u^3x^7y^5$ and $30u^4x^6$, we need to identify the common factors of the two expressions. The common factors are the factors that appear in both expressions.

In the given expressions, the common factors are:

• $u^3$ and $u^4$ (both expressions have a variable $u$ raised to a power)
• $x^6$ and $x^7$ (both expressions have a variable $x$ raised to a power)

However, we need to be careful when identifying the common factors. We can only take the lowest power of each common factor. In this case, the lowest power of $u$ is $u^3$, and the lowest power of $x$ is $x^6$.

Step 2: Multiply the Common Factors

---

Now that we have identified the common factors, we need to multiply them together to find the GCF.

The GCF of $18u^3x^7y^5$ and $30u^4x^6$ is:

$2 \cdot u^3 \cdot x^6$

Simplifying the GCF

---

We can simplify the GCF by multiplying the numerical coefficients together.

The numerical coefficients of the two expressions are 18 and 30. The greatest common factor of 18 and 30 is 6.

Therefore, the simplified GCF is:

$6u^3x^6$

In this article, we learned how to find the greatest common factor (GCF) of two algebraic expressions: $18u^3x^7y^5$ and $30u^4x^6$. We identified the common factors of the two expressions, multiplied them together, and simplified the result to find the GCF.

GCF of Multiple Expressions

---

The GCF of multiple expressions is the largest expression that divides each of the given expressions without leaving a remainder. To find the GCF of multiple expressions, we need to identify the common factors of the expressions and multiply them together.

For example, let's find the GCF of $18u^3x^7y^5$, $30u^4x^6$, and $24u^2x^3y^4$.

The common factors of the three expressions are:

• $u^3$ and $u^4$ (all expressions have a variable $u$ raised to a power)
• $x^6$ and $x^7$ (all expressions have a variable $x$ raised to a power)

However, we need to be careful when identifying the common factors. We can only take the lowest power of each common factor. In this case, the lowest power of $u$ is $u^3$, and the lowest power of $x$ is $x^6$.

The GCF of $18u^3x^7y^5$, $30u^4x^6$, and $24u^2x^3y^4$ is:

$2 \cdot u^3 \cdot x^6$

We can simplify the GCF by multiplying the numerical coefficients together.

The numerical coefficients of the three expressions are 18, 30, and 24. The greatest common factor of 18, 30, and 24 is 6.

Therefore, the simplified GCF is:

$6u^3x^6$

Real-World Applications

The GCF of algebraic expressions has many real-world applications. For example, in engineering, the GCF of two or more equations can be used to simplify complex systems and solve problems.

In finance, the GCF of two or more financial instruments can be used to determine the risk associated with each instrument.
