GCF of Denominators means GCF of 640,998 as per the given fractions.

GCF of 640,998 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 389,8105

LCM of Fractions 389/640,8105/998 is 3152845/2

Given numbers has no common factors except 1. So, there LCM is their product i.e 3152845

Least Common Multiple of 389,8105 with GCF Formula

Least Common Multiple of 389,8105 with GCF Formula

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 389,8105 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(389,8105) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(389,8105) x common factors =1 x 1 = 1

LCM(389,8105) = ( 389 × 8105 ) / 1

LCM(389,8105) = 3152845 / 1

LCM(389,8105) = 3152845


Lets's calculate GCF of 640,998

2 640, 998
320, 499

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3152845/2

Therefore the LCM of Fractions 389/640,8105/998 is 3152845/2
