Factors of 105
List of positive integer factors of 105 that divides 105 without a remainder.
1, 3, 5, 7, 15, 21, 35, 105
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 101 and 105, than apply into the LCM equation.
GCF(101,105) = 1
LCM(101,105) = ( 101 × 105) / 1
LCM(101,105) = 10605 / 1
LCM(101,105) = 10605
(i) The LCM of 105 and 101 is associative
