CALCULATION DESK
Apply the Euclidean algorithm across a list of positive integers to find their greatest common divisor.
WHAT THIS DOES
Runs entirely in your browser.
/tools/gcd-calculatorgcd-calcv4.0.0LOCAL · LOCAL RUNIMPLEMENTED — This workbench is functional in the current release.Presets for this workbench
No preset yet. A preset stores the values in this form — never the result — and only for workbenches that run entirely in your browser.
Collections
Saved on this device only. Turn on sync to carry them to another device.
BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of numbers and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
GCD(a, b) = GCD(b, a mod b) until b = 0. Reduce across a list.
Boundary: Positive integers only. Zero is treated as the identity: GCD(0, n) = n.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
No. The GCD calculator runs locally.
The workbench states the exact method behind every result — the formula or procedure this page runs — so you can verify the computation instead of trusting a black box.
No. This workbench runs in the page: Numbers (space-separated) are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: Numbers (space-separated) (1,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
Positive integers only. Zero is treated as the identity: GCD(0, n) = n.
