The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 22 and 14, than apply into the LCM equation.
GCF(22,14) = 2
LCM(22,14) = ( 22 × 14) / 2
LCM(22,14) = 308 / 2
LCM(22,14) = 154
(i) The LCM of 14 and 22 is associative
LCM of 22 and 14 = LCM of 14 and 22
