Lets's calculate LCM of 78,4387
Given numbers has no common factors except 1. So, there LCM is their product i.e 342186
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/342186
Therefore, the GCF of Fractions 578/78,768/4387 is 2/342186
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 78,4387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,4387) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(78,4387) x common factors =1 x 1 = 1
LCM(78,4387) = ( 78 × 4387 ) / 1
LCM(78,4387) = 342186 / 1
LCM(78,4387) = 342186
