How it works
Use Euclid’s algorithm for GCD and LCM(a,b)=abs(a×b)/GCD(a,b); fold across all inputs.

Common questions
Why can statistical results differ between tools?
Denominator, interpolation and boundary conventions can differ. Use the method and assumptions on this page to compare the same definition; displayed decimals may also be rounded.
