GCF of Denominators means GCF of 61,38,85 as per the given fractions.

GCF of 61,38,85 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 128,239,677

LCM of Fractions 128/61,239/38,677/85 is 20710784

Given numbers has no common factors except 1. So, there LCM is their product i.e 20710784

Least Common Multiple of 128,239,677 with GCF Formula

Least Common Multiple of 128,239,677 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 128,239,677 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(128,239,677) = 1

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

GCF(128,239,677) x common factors =1 x 1 = 1

LCM(128,239,677) = ( 128 × 239 × 677 ) / 1

LCM(128,239,677) = 20710784 / 1

LCM(128,239,677) = 20710784


Lets's calculate GCF of 61,38,85

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 20710784/1

Therefore the LCM of Fractions 128/61,239/38,677/85 is 20710784
