As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 128,1949

Least Common Multiple of Numerators i.e. LCM of 128,1949 is 249472.

GCF of Denominators means GCF of 891,391 as per the given fractions.

GCF of 891,391 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 128,1949

LCM of Fractions 128/891,1949/391 is 249472

Given numbers has no common factors except 1. So, there LCM is their product i.e 249472

Least Common Multiple of 128,1949 with GCF Formula

Least Common Multiple of 128,1949 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 128,1949 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(128,1949) = 1

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

GCF(128,1949) x common factors =1 x 1 = 1

LCM(128,1949) = ( 128 × 1949 ) / 1

LCM(128,1949) = 249472 / 1

LCM(128,1949) = 249472


Lets's calculate GCF of 891,391

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 249472/1

Therefore the LCM of Fractions 128/891,1949/391 is 249472
