Least Common Multiple of 2018 and 2037 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2018 and 2037, than apply into the LCM equation.

GCF(2018,2037) = 1
LCM(2018,2037) = ( 2018 × 2037) / 1
LCM(2018,2037) = 4110666 / 1
LCM(2018,2037) = 4110666

Least Common Multiple (LCM) of 2018 and 2037 with Primes
