Least Common Multiple of 2012 and 2018 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2012 and 2018, than apply into the LCM equation.

GCF(2012,2018) = 2
LCM(2012,2018) = ( 2012 × 2018) / 2
LCM(2012,2018) = 4060216 / 2
LCM(2012,2018) = 2030108
