Least Common Multiple of 11/56,78/57,71/28

Given numbers are 11/56,78/57,71/28

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 11,78,71

Least Common Multiple of Numerators i.e. LCM of 11,78,71 is 60918.

GCF of Denominators means GCF of 56,57,28 as per the given fractions.

GCF of 56,57,28 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 11,78,71

LCM of Fractions 11/56,78/57,71/28 is 60918

Given numbers has no common factors except 1. So, there LCM is their product i.e 60918

Least Common Multiple of 11,78,71 with GCF Formula

Least Common Multiple of 11,78,71 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 11,78,71 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(11,78,71) = 1

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

GCF(11,78,71) x common factors =1 x 1 = 1

LCM(11,78,71) = ( 11 × 78 × 71 ) / 1

LCM(11,78,71) = 60918 / 1

LCM(11,78,71) = 60918


Lets's calculate GCF of 56,57,28

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 60918/1

Therefore the LCM of Fractions 11/56,78/57,71/28 is 60918
