Least Common Multiple of 2600 and 2611 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2600 and 2611, than apply into the LCM equation.

GCF(2600,2611) = 1
LCM(2600,2611) = ( 2600 × 2611) / 1
LCM(2600,2611) = 6788600 / 1
LCM(2600,2611) = 6788600
