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 217,1287

Least Common Multiple of Numerators i.e. LCM of 217,1287 is 279279.

GCF of Denominators means GCF of 243,511 as per the given fractions.

GCF of 243,511 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 217,1287

LCM of Fractions 217/243,1287/511 is 279279

Given numbers has no common factors except 1. So, there LCM is their product i.e 279279

Least Common Multiple of 217,1287 with GCF Formula

Least Common Multiple of 217,1287 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 217,1287 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(217,1287) = 1

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

GCF(217,1287) x common factors =1 x 1 = 1

LCM(217,1287) = ( 217 × 1287 ) / 1

LCM(217,1287) = 279279 / 1

LCM(217,1287) = 279279


Lets's calculate GCF of 243,511

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 279279/1

Therefore the LCM of Fractions 217/243,1287/511 is 279279
