Answer for screen readers
The greatest common factor (GCF) of $75$ and $125$ is $25$.
Steps to Solve
- List the factors of each number
First, we need to identify the factors of both numbers.
- The factors of $75$ are $1, 3, 5, 15, 25, 75$.
- The factors of $125$ are $1, 5, 25, 125$.
- Identify the common factors
Next, we will find the factors that are common between the two lists:
- The common factors of $75$ and $125$ are $1, 5, 25$.
- Determine the greatest common factor
To find the greatest common factor, we compare the common factors and identify the largest one:
- The largest common factor is $25$.
The greatest common factor (GCF) of $75$ and $125$ is $25$.
More Information
The GCF is useful in simplifying fractions, finding equivalent ratios, and solving problems involving least common multiples. It's a fundamental concept in number theory and helps in various applications in math.
Tips
- Forgetting to list all factors may lead to missing the GCF. Make sure to write down all factors carefully.
- Overlooking the largest common factor by misidentifying it among shared factors. Always double-check comparisons.
