GCF Calculator: Simple and Accurate

Enter numbers separated by commas to find their Greatest Common Factor (GCF) and Least Common Multiple (LCM):

How to Use:

  • Enter two or more positive integers separated by commas
  • Click "Calculate" to find both GCF and LCM
  • GCF is the largest number that divides all input numbers evenly
  • LCM is the smallest number that all input numbers divide into evenly

This calculator finds the greatest common factor and the least common multiple of positive integers. It uses a straightforward method for quick results.

How to Use This Tool

  1. Enter two or more positive integers in the text box. Use commas to separate each number. For example, enter "12, 18, 24".
  2. Press the Calculate button. This step processes your numbers.
  3. View the results. The tool shows both the greatest common factor and the least common multiple.

If the tool finds an error, it shows a red message. This tells you what to fix.

Understanding the Input Field

The input field accepts only positive integers. Do not use any letters or negative numbers. The numbers must be separated by commas.

Interpreting the Output

The results include two parts:

If you see a red error message, check your input and try again.

Limitations and Special Notes

This tool works with positive integers only. It does not process decimals or negative numbers. Enter at least two numbers for a valid result.

Common Use Cases

Students use this tool for homework and exam preparation. Teachers use it to generate examples in class. Everyday math problems can also be solved quickly with it.
