1, 2, 4, 8, 13, 26, 52, 104
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 100 and 104, than apply into the LCM equation.
GCF(100,104) = 4
LCM(100,104) = ( 100 × 104) / 4
LCM(100,104) = 10400 / 4
LCM(100,104) = 2600
(i) The LCM of 104 and 100 is associative
LCM of 100 and 104 = LCM of 104 and 100
