Lets's calculate LCM of 249,512
Given numbers has no common factors except 1. So, there LCM is their product i.e 127488
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/127488
Therefore, the GCF of Fractions 3870/249,7935/512 is 15/127488
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 249,512 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(249,512) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(249,512) x common factors =1 x 1 = 1
LCM(249,512) = ( 249 × 512 ) / 1
LCM(249,512) = 127488 / 1
LCM(249,512) = 127488
