Introduction

In mathematics, the greatest common factor (GCF) is a fundamental concept used to simplify algebraic expressions. It is essential to understand how to find the GCF of two or more expressions, as it helps in factoring and simplifying complex expressions. In this article, we will focus on finding the GCF of two algebraic expressions, $$96x^5$$ and $$64x^2$$.

Step 1: Finding the GCF of the Numerical Coefficients

To find the GCF of the given expressions, we first need to find the GCF of the numerical coefficients, which are 96 and 64.

GCF of 96 and 64

To find the GCF of 96 and 64, we can use the prime factorization method. We start by expressing each number as a product of its prime factors.

64 = (2)(2)(2)(2)(2)(2)
96 = (2)(2)(2)(2)(2)(3)

By comparing the prime factorizations of 96 and 64, we can see that the common factors are the product of 2's, which is 32.

GCF = (2)(2)(2)(2)(2) = 32

Step 2: Finding the GCF of the Variable Terms

Now that we have found the GCF of the numerical coefficients, we need to find the GCF of the variable terms, which are $$x^5$$ and $$x^2$$.

GCF of $$x^5$$ and $$x^2$$

To find the GCF of $$x^5$$ and $$x^2$$, we need to identify the common variable term. In this case, the common variable term is $$x^2$$.

GCF of variable terms = x^2

Step 3: Combining the GCF of Numerical Coefficients and Variable Terms

Now that we have found the GCF of the numerical coefficients and the variable terms, we can combine them to find the GCF of the given expressions.

GCF of 96x^5 and 64x^2 = GCF of numerical coefficients × GCF of variable terms
= 32 × x^2
= 32x^2

Conclusion

In conclusion, the GCF of $$96x^5$$ and $$64x^2$$ is $$32x^2$$. This is obtained by finding the GCF of the numerical coefficients, which is 32, and the GCF of the variable terms, which is $$x^2$$. By combining these two GCFs, we get the final GCF of the given expressions.
