Factors of 10005
List of positive integer factors of 10005 that divides 10005 without a remainder.
1, 3, 5, 15, 23, 29, 69, 87, 115, 145, 345, 435, 667, 2001, 3335, 10005
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10000 and 10005, than apply into the LCM equation.
GCF(10000,10005) = 5
LCM(10000,10005) = ( 10000 × 10005) / 5
LCM(10000,10005) = 100050000 / 5
LCM(10000,10005) = 20010000
(i) The LCM of 10005 and 10000 is associative
