About this tool: GCD and LCM Calculator
Find the greatest common divisor and least common multiple of a list of signed integers.
Enter signed integers separated by spaces, line breaks or semicolons. Signs are ignored for GCD and LCM; any zero makes the LCM zero, and an all-zero list has GCD zero. The Euclidean algorithm and integer arithmetic avoid rounding large values.
