About This Calculator
LCM is used to add fractions with different denominators and to find the period of repeating events. If event A repeats every 12 days and event B every 8 days, they next coincide in LCM(12,8) = 24 days. LCM has applications in gear ratios, music rhythm, and scheduling problems.
