The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 56 and 10, than apply into the LCM equation.
GCF(56,10) = 2
LCM(56,10) = ( 56 × 10) / 2
LCM(56,10) = 560 / 2
LCM(56,10) = 280
(i) The LCM of 10 and 56 is associative
LCM of 56 and 10 = LCM of 10 and 56
