Factors of 8
List of positive integer factors of 8 that divides 8 without a remainder.
1, 2, 4, 8
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 24 and 8, than apply into the LCM equation.
GCF(24,8) = 8
LCM(24,8) = ( 24 × 8) / 8
LCM(24,8) = 192 / 8
LCM(24,8) = 24
(i) The LCM of 8 and 24 is associative
LCM of 24 and 8 = LCM of 8 and 24
