Introduction

In mathematics, the greatest common factor (GCF) is a fundamental concept used to find the largest positive integer that divides two or more numbers without leaving a remainder. When dealing with algebraic expressions, identifying the GCF becomes a crucial step in simplifying and solving equations. In this article, we will explore how to find the GCF of two algebraic expressions, specifically the GCF of $10wx$ and $29z$.

Understanding the Concept of GCF

The GCF of two numbers is the largest positive integer that divides both numbers without leaving a remainder. For example, the GCF of 12 and 18 is 6, since 6 is the largest number that divides both 12 and 18 without leaving a remainder. Similarly, the GCF of two algebraic expressions is the largest expression that divides both expressions without leaving a remainder.

Identifying the GCF of Algebraic Expressions

To identify the GCF of two algebraic expressions, we need to follow these steps:

  1. Factorize the expressions: Factorize both expressions into their prime factors.
  2. Identify common factors: Identify the common factors between the two expressions.
  3. Multiply common factors: Multiply the common factors to find the GCF.

Finding the GCF of $10wx$ and $29z$

To find the GCF of $10wx$ and $29z$, we need to follow the steps outlined above.

Step 1: Factorize the expressions

10wx=2×5×w×x10wx = 2 \times 5 \times w \times x

29z=29×z29z = 29 \times z

Step 2: Identify common factors

There are no common factors between $10wx$ and $29z$, since they have different prime factors.

Step 3: Multiply common factors

Since there are no common factors, the GCF of $10wx$ and $29z$ is 1.

Conclusion

In conclusion, identifying the GCF of algebraic expressions is a crucial step in simplifying and solving equations. By following the steps outlined above, we can find the GCF of two algebraic expressions. In this article, we found that the GCF of $10wx$ and $29z$ is 1, since they have no common factors.
