CI Gcf calculator

This calculator finds the greatest common factor (GCF) of any set of positive integers. It is designed for students, teachers, and anyone who needs to quickly determine the largest number that divides evenly into a group of numbers.

• Step-by-step solutions: The calculator shows the full process for finding the GCF, using factorization, prime factorization, or Euclid's algorithm. You can see exactly how the result is reached.
• Lists all factors: For each number you enter, the tool displays every factor. This helps you understand the relationship between the numbers and their common divisors.
• Handles multiple numbers: Enter any set of numbers separated by commas or spaces. The tool works for two or more numbers at once.
• Supports zero: The calculator correctly handles cases where one number is zero, returning the absolute value of the non-zero number as the GCF.
• Clear error handling: If you enter invalid input (like non-integers or all zeros), the tool shows a clear error message instead of failing silently.
