How to use it

Separate your integers with commas, spaces or new lines. The result is the largest positive integer that divides every input without a remainder.

A worked example

The greatest common factor of 48 and 180 is 12. For -18, 24 and 0, the answer is 6.

What to know

This tool uses exact integer arithmetic for up to 100 entries, each at most 100 digits. Negative values use their absolute magnitude. A list containing only zeros has no greatest positive factor.
