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 797,2720

Least Common Multiple of Numerators i.e. LCM of 797,2720 is 2167840.

GCF of Denominators means GCF of 861,145 as per the given fractions.

GCF of 861,145 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 797,2720

LCM of Fractions 797/861,2720/145 is 2167840

Given numbers has no common factors except 1. So, there LCM is their product i.e 2167840

Least Common Multiple of 797,2720 with GCF Formula

Least Common Multiple of 797,2720 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 797,2720 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(797,2720) = 1

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

GCF(797,2720) x common factors =1 x 1 = 1

LCM(797,2720) = ( 797 × 2720 ) / 1

LCM(797,2720) = 2167840 / 1

LCM(797,2720) = 2167840


Lets's calculate GCF of 861,145

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2167840/1

Therefore the LCM of Fractions 797/861,2720/145 is 2167840
