THIS IS ANCIENT VERSION OF CALCULLA.COM LEFT HERE FOR ARCHIVAL PURPOSES.
ALL CALCULATORS SHOULD STILL WORK, BUT YOU CAN'T BE SURE. WE ALSO DON'T UPDATE THEM, SO EXPECT OUTDATED INFO.
OUR SUGGESTION IS TO MOVE TO RECENT VERSION OF CALCULLA.COM BY CLICKING THE LINK: GCD
Greatest Common Divisor (GCD) calculator - solves GCD for given numbers, but also displays prime dividers (in a school-like way). So, you know how the solution is found. It can find the GCD for 3 numbers too !
- Greatest Common Divisor is the largest positive integer that divides two or more numbers without remainder
- Greatest Common Divisor (GCD) is also known as Greatest Common Factor (GCF) and Highest Common Factor (HCF)
- GCD is mainly useful for reducing fractions to be in lowest terms possible.
How to use this tool
To search for greatest common divisor or least common multiplier enter your numbers into fields below.
You can enter 2 or 3 integer numbers. If you need only 2 of them - just leave 3rd field empty!
All numbers should be non-zero integer (so you can use negative numbers).
If you need only 2 numbers - just leave 3rd field empty!
