Frequently asked questions
- Can GCD take more than two numbers?
- Yes. Enter 2, 3 or more integers separated by commas or spaces.
- Are GCD and MDC the same?
- Yes. MDC is the Portuguese name for greatest common divisor.
- What if one number is 1?
- The GCD will be 1, because 1 only divides and is divided by 1.
- Is the calculation on a server?
- No. It runs in the browser.
