1, 251
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 250 and 251, than apply into the LCM equation.
GCF(250,251) = 1
LCM(250,251) = ( 250 × 251) / 1
LCM(250,251) = 62750 / 1
LCM(250,251) = 62750
(i) The LCM of 251 and 250 is associative
LCM of 250 and 251 = LCM of 251 and 250
