Calculate the Greatest Common Divisor of 2-10 numbers using Euclidean Algorithm or Prime Factorization. See step-by-step solutions and learn practical applications.
Enter numbers and calculate to see the GCD
The Greatest Common Divisor (GCD) calculator is a powerful tool for finding the largest number that divides all given numbers evenly. Whether you're simplifying fractions, solving number theory problems, or working on cryptography, understanding GCD is essential.
The GCD is the largest positive integer that divides each of the numbers without a remainder. For example, the GCD of 12 and 18 is 6, because 6 is the largest number that divides both 12 and 18 evenly.

“This GCD calculator is perfect for teaching students! The step-by-step Euclidean algorithm breakdown helps them understand the process, not just get the answer. The prime factorization method is great for visual learners.”
“Saved me so much time on my discrete mathematics homework. Being able to see both calculation methods side-by-side helped me verify my work and understand which method is more efficient for different problems.”
“Use this for algorithm design and cryptography work. The ability to calculate GCD of up to 10 numbers at once is incredibly useful. The export feature lets me save calculations for documentation. Excellent tool!”
