Least Common Multiple of 24 and 38 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 24 and 38, than apply into the LCM equation.

GCF(24,38) = 2
LCM(24,38) = ( 24 × 38) / 2
LCM(24,38) = 912 / 2
LCM(24,38) = 456

Least Common Multiple (LCM) of 24 and 38 with Primes
