Least Common Multiple of 2100 and 2111 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2100 and 2111, than apply into the LCM equation.

GCF(2100,2111) = 1
LCM(2100,2111) = ( 2100 × 2111) / 1
LCM(2100,2111) = 4433100 / 1
LCM(2100,2111) = 4433100

Least Common Multiple (LCM) of 2100 and 2111 with Primes
