Lets's calculate LCM of 515,963
Given numbers has no common factors except 1. So, there LCM is their product i.e 495945
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/495945
Therefore, the GCF of Fractions 660/515,7138/963 is 2/495945
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 515,963 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(515,963) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(515,963) x common factors =1 x 1 = 1
LCM(515,963) = ( 515 × 963 ) / 1
LCM(515,963) = 495945 / 1
LCM(515,963) = 495945
