In mathematics, the greatest common factor (GCF) is a fundamental concept used to simplify algebraic expressions. It is the largest expression that divides two or more expressions without leaving a remainder. In this article, we will explore how to find the GCF of two algebraic expressions, specifically the expressions $15u^6w^4y^7$ and $30u^6w^5$.

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: Identify the Common Factors

To find the GCF of the expressions $15u^6w^4y^7$ and $30u^6w^5$, we need to identify the common factors of the expressions. The common factors are the factors that appear in both expressions.

• The first expression is $15u^6w^4y^7$, which can be factored as $3 \cdot 5 \cdot u^6 \cdot w^4 \cdot y^7$.
• The second expression is $30u^6w^5$, which can be factored as $2 \cdot 3 \cdot 5 \cdot u^6 \cdot w^5$.

The common factors of the expressions are $3$, $5$, and $u^6$.

Step 2: Multiply the Common Factors

To find the GCF, we need to multiply the common factors together. The GCF is the product of the common factors.

• The GCF of the expressions $15u^6w^4y^7$ and $30u^6w^5$ is $3 \cdot 5 \cdot u^6 = 15u^6$.

Conclusion

In conclusion, the GCF of the expressions $15u^6w^4y^7$ and $30u^6w^5$ is $15u^6$. The GCF is the largest expression that divides both expressions without leaving a remainder. It is used to simplify algebraic expressions and is a fundamental concept in mathematics.

Example Use Case
