## Least Common Multiple of 8 and 23 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 8 and 23, than apply into the LCM equation.

GCF(8,23) = 1
LCM(8,23) = ( 8 × 23) / 1
LCM(8,23) = 184 / 1
LCM(8,23) = 184

## Least Common Multiple (LCM) of 8 and 23 with Primes
