So the greatest common factor 791,664 is 1.
Lets's calculate LCM of 243,386
Given numbers has no common factors except 1. So, there LCM is their product i.e 93798
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/93798
Therefore, the GCF of Fractions 791/243,664/386 is 1/93798
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 243,386 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,386) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(243,386) x common factors =1 x 1 = 1
LCM(243,386) = ( 243 × 386 ) / 1
LCM(243,386) = 93798 / 1
LCM(243,386) = 93798
