The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 43 and 50, than apply into the LCM equation.
GCF(43,50) = 1
LCM(43,50) = ( 43 × 50) / 1
LCM(43,50) = 2150 / 1
LCM(43,50) = 2150
(i) The LCM of 50 and 43 is associative
LCM of 43 and 50 = LCM of 50 and 43
