Factors of 2731
List of positive integer factors of 2731 that divides 2731 without a remainder.
1, 2731
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2730 and 2731, than apply into the LCM equation.
GCF(2730,2731) = 1
LCM(2730,2731) = ( 2730 × 2731) / 1
LCM(2730,2731) = 7455630 / 1
LCM(2730,2731) = 7455630
(i) The LCM of 2731 and 2730 is associative
LCM of 2730 and 2731 = LCM of 2731 and 2730
