So the greatest common factor 386,347 is 1.
Lets's calculate LCM of 909,781
Given numbers has no common factors except 1. So, there LCM is their product i.e 709929
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/709929
Therefore, the GCF of Fractions 386/909,347/781 is 1/709929
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 909,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(909,781) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(909,781) x common factors =1 x 1 = 1
LCM(909,781) = ( 909 × 781 ) / 1
LCM(909,781) = 709929 / 1
LCM(909,781) = 709929
