Lets's calculate LCM of 486,473
Given numbers has no common factors except 1. So, there LCM is their product i.e 229878
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/229878
Therefore, the GCF of Fractions 781/486,308/473 is 11/229878
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 486,473 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(486,473) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(486,473) x common factors =1 x 1 = 1
LCM(486,473) = ( 486 × 473 ) / 1
LCM(486,473) = 229878 / 1
LCM(486,473) = 229878
