Lets's calculate LCM of 389,570,983
Given numbers has no common factors except 1. So, there LCM is their product i.e 217960590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/217960590
Therefore, the GCF of Fractions 54/389,11/570,969/983 is 1/217960590
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 389,570,983 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,570,983) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(389,570,983) x common factors =1 x 1 = 1
LCM(389,570,983) = ( 389 × 570 × 983 ) / 1
LCM(389,570,983) = 217960590 / 1
LCM(389,570,983) = 217960590
