The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10001 and 10005, than apply into the LCM equation.
GCF(10001,10005) = 1
LCM(10001,10005) = ( 10001 × 10005) / 1
LCM(10001,10005) = 100060005 / 1
LCM(10001,10005) = 100060005
(i) The LCM of 10005 and 10001 is associative
