Least Common Multiple of 10100 and 10110 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10100 and 10110, than apply into the LCM equation.

GCF(10100,10110) = 10
LCM(10100,10110) = ( 10100 × 10110) / 10
LCM(10100,10110) = 102111000 / 10
LCM(10100,10110) = 10211100
