Least Common Multiple of 409/861,1340/477

Given numbers are 409/861,1340/477

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

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 409,1340

Least Common Multiple of Numerators i.e. LCM of 409,1340 is 548060.

GCF of Denominators means GCF of 861,477 as per the given fractions.

GCF of 861,477 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 409,1340

LCM of Fractions 409/861,1340/477 is 548060/3

Given numbers has no common factors except 1. So, there LCM is their product i.e 548060

Least Common Multiple of 409,1340 with GCF Formula

Least Common Multiple of 409,1340 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 409,1340 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(409,1340) = 1

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

GCF(409,1340) x common factors =1 x 1 = 1

LCM(409,1340) = ( 409 × 1340 ) / 1

LCM(409,1340) = 548060 / 1

LCM(409,1340) = 548060


Lets's calculate GCF of 861,477

3 861, 477
287, 159

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 548060/3

Therefore the LCM of Fractions 409/861,1340/477 is 548060/3
