Least Common Multiple of 29 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 29 and 38, than apply into the LCM equation.

GCF(29,38) = 1
LCM(29,38) = ( 29 × 38) / 1
LCM(29,38) = 1102 / 1
LCM(29,38) = 1102

Least Common Multiple (LCM) of 29 and 38 with Primes
