Factors of 48
List of positive integer factors of 48 that divides 48 without a remainder.
1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Factors of 50
List of positive integer factors of 50 that divides 50 without a remainder.
1, 2, 5, 10, 25, 50
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 48 and 50, than apply into the LCM equation.
GCF(48,50) = 2
LCM(48,50) = ( 48 × 50) / 2
LCM(48,50) = 2400 / 2
LCM(48,50) = 1200
(i) The LCM of 50 and 48 is associative
