Method
lcm(a,b) = |(a/gcd(a,b))b|, folded across the list. Division before multiplication reduces intermediate growth.

Least Common Multiple Calculator
Find the smallest nonnegative multiple shared by an integer list and audit each Euclidean-algorithm fold.
The calculation runs locally. Exact-integer tools avoid floating point; decimal and transcendental tools report rounding limits.

How the Least Common Multiple Calculator works
lcm(a,b) = |(a/gcd(a,b))b|, folded across the list. Division before multiplication reduces intermediate growth. The calculator keeps the intermediate values visible so you can reproduce the answer independently.
Interpret the result
Every input divides the LCM exactly; zero makes the conventional nonnegative LCM zero.
Check the assumptions
This browser worksheet accepts ordinary exact integers within JavaScript's safe-integer range for responsive display.
Local calculation
Everything runs in this browser. Inputs are not sent to an external calculator.
Rounding
Displayed values may be rounded for readability while calculations use full floating-point precision unless the tool explicitly uses exact integers.
