Introduction

Mathematics is a fascinating subject that involves solving equations, identifying patterns, and unraveling mysteries. In this article, we will delve into the world of mathematics and explore the concept of the greatest common factor (GCF) and its application in rewriting an equation as a product of the GCF and a sum. We will also examine the missing number in the equation and determine which statements are true.

Understanding the Greatest Common Factor (GCF)

The greatest common factor (GCF) is the largest positive integer that divides two or more numbers without leaving a remainder. It is an essential concept in mathematics, particularly in algebra and number theory. The GCF is used to simplify fractions, find the least common multiple (LCM), and solve equations.

Rewriting the Equation as a Product of the GCF and a Sum

To rewrite the equation $80 + 260$ as a product of the GCF and a sum, we need to find the GCF of 80 and 260. The GCF of 80 and 260 is 20. Now, we can rewrite the equation as:

80 + 260 = 20 \times (4 + 13)

In this equation, 20 is the GCF, and $(4 + 13)$ is the sum.

The Missing Number in the Equation

The equation $75 + 1,000 = ?$ is a simple addition problem. To find the missing number, we need to add 75 and 1,000. The result is:

75 + 1,000 = 1,075

Analyzing the Statements

Now, let's analyze the statements and determine which ones are true.

The GCF is 20: This statement is true. The GCF of 80 and 260 is indeed 20.
The sum is 4 + 13: This statement is true. The sum of 4 and 13 is indeed 17.
The equation can be rewritten as 20 × 17: This statement is true. The equation can be rewritten as 20 × 17.
The missing number in the equation is 1,075: This statement is true. The missing number in the equation is indeed 1,075.

Conclusion

In conclusion, the GCF is an essential concept in mathematics that is used to simplify fractions, find the LCM, and solve equations. By rewriting the equation $80 + 260$ as a product of the GCF and a sum, we can simplify the equation and make it easier to solve. Additionally, we can determine the missing number in the equation $75 + 1,000 = ?$ by adding 75 and 1,000. We hope this article has provided valuable insights into the world of mathematics and has helped you understand the concept of the GCF and its application in rewriting an equation as a product of the GCF and a sum.
