Lets's calculate LCM of 647,6610
Given numbers has no common factors except 1. So, there LCM is their product i.e 4276670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/4276670
Therefore, the GCF of Fractions 7830/647,2165/6610 is 5/4276670
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 647,6610 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(647,6610) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(647,6610) x common factors =1 x 1 = 1
LCM(647,6610) = ( 647 × 6610 ) / 1
LCM(647,6610) = 4276670 / 1
LCM(647,6610) = 4276670
