Least Common Multiple of 19001 and 19008 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 19001 and 19008, than apply into the LCM equation.

GCF(19001,19008) = 1
LCM(19001,19008) = ( 19001 × 19008) / 1
LCM(19001,19008) = 361171008 / 1
LCM(19001,19008) = 361171008

Least Common Multiple (LCM) of 19001 and 19008 with Primes
