Understanding the Concept of Greatest Common Factor (GCF)

The Greatest Common Factor (GCF) is a mathematical concept that represents the largest expression that divides each of the given expressions without leaving a remainder. In other words, it is the product of the common factors of the given expressions. The GCF is an essential concept in algebra, and it plays a crucial role in simplifying complex expressions.

Breaking Down the Given Expressions

To find the GCF of $16s^3t$ , $40s^5$ , and $68t^2$ , we need to break down each expression into its prime factors. This will help us identify the common factors and determine the GCF.

Prime Factorization of $16s^3t$

The prime factorization of $16s^3t$ is:

16s^3t = 2^4 \cdot s^3 \cdot t

Prime Factorization of $40s^5$

The prime factorization of $40s^5$ is:

40s^5 = 2^3 \cdot 5 \cdot s^5

Prime Factorization of $68t^2$

The prime factorization of $68t^2$ is:

68t^2 = 2^2 \cdot 17 \cdot t^2

Identifying the Common Factors

Now that we have the prime factorization of each expression, we can identify the common factors. The common factors are the factors that appear in all three expressions.

The common factors of $16s^3t$ , $40s^5$ , and $68t^2$ are:

$2^2$
$t$

Determining the Greatest Common Factor (GCF)

The GCF is the product of the common factors. In this case, the GCF is:

\text{GCF} = 2^2 \cdot t = 4t

However, we need to consider the exponents of the variables $s$ and $t$ . The expression with the lowest exponent of $s$ is $16s^3t$ , which has an exponent of $3$ . Therefore, the GCF should include $s^3$ .

The final answer is: $\boxed{4s^3t}$
