So the greatest common factor 385,912 is 1.
Lets's calculate LCM of 122,857
Given numbers has no common factors except 1. So, there LCM is their product i.e 104554
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/104554
Therefore, the GCF of Fractions 385/122,912/857 is 1/104554
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 122,857 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(122,857) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(122,857) x common factors =1 x 1 = 1
LCM(122,857) = ( 122 × 857 ) / 1
LCM(122,857) = 104554 / 1
LCM(122,857) = 104554
