Least Common Multiple of 2019 and 2034 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2019 and 2034, than apply into the LCM equation.

GCF(2019,2034) = 3
LCM(2019,2034) = ( 2019 × 2034) / 3
LCM(2019,2034) = 4106646 / 3
LCM(2019,2034) = 1368882
