Least Common Multiple of 30001 and 30008 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 30001 and 30008, than apply into the LCM equation.

GCF(30001,30008) = 1
LCM(30001,30008) = ( 30001 × 30008) / 1
LCM(30001,30008) = 900270008 / 1
LCM(30001,30008) = 900270008

Least Common Multiple (LCM) of 30001 and 30008 with Primes
