The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 27 and 10, than apply into the LCM equation.
GCF(27,10) = 1
LCM(27,10) = ( 27 × 10) / 1
LCM(27,10) = 270 / 1
LCM(27,10) = 270
(i) The LCM of 10 and 27 is associative
LCM of 27 and 10 = LCM of 10 and 27
