So the greatest common factor 819,406 is 7.
Lets's calculate LCM of 389,985
Given numbers has no common factors except 1. So, there LCM is their product i.e 383165
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/383165
Therefore, the GCF of Fractions 819/389,406/985 is 7/383165
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 389,985 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,985) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(389,985) x common factors =1 x 1 = 1
LCM(389,985) = ( 389 × 985 ) / 1
LCM(389,985) = 383165 / 1
LCM(389,985) = 383165
