Greatest Common Divisor Calculator

GCD Calculator Introduction

The GCD Calculator is a simple and easy-to-use online tool for calculating the common divisors and the greatest common divisor (GCD) of multiple positive integers.

Based on a set of input numbers, it quickly retrieves their list of common divisors and the greatest common divisor. This tool is suitable for mathematical learning, algorithm verification, or daily calculation needs, helping users efficiently complete related computations.

How to Use the GCD Calculator

Enter numbers: Input multiple positive integers in the input box, separated by spaces, commas, or semicolons (e.g., 12, 18, 24 or 12 18 24).
Click Calculate: Press the "Calculate" button, and the tool will automatically compute and display:

• Common Divisors (all shared divisors of the numbers, e.g., 1, 2, 3, 6)
• Greatest Common Divisor (GCD) (the largest shared divisor, e.g., 6)

Copy Result (optional): Click the "Copy" button to copy the result to your clipboard.
Click "Example": The system will automatically generate a set of random numbers (e.g., 15, 30, 45).
