1, 3, 677, 2031
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2030 and 2031, than apply into the LCM equation.
GCF(2030,2031) = 1
LCM(2030,2031) = ( 2030 × 2031) / 1
LCM(2030,2031) = 4122930 / 1
LCM(2030,2031) = 4122930
(i) The LCM of 2031 and 2030 is associative
