Least Common Multiple of 2686/20,7721/940

Given numbers are 2686/20,7721/940

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 2686,7721

Least Common Multiple of Numerators i.e. LCM of 2686,7721 is 20738606.

GCF of Denominators means GCF of 20,940 as per the given fractions.

GCF of 20,940 is 20 as it is the largest common factor for these numbers.

Lets's calculate LCM of 2686,7721

LCM of Fractions 2686/20,7721/940 is 20738606/20

Given numbers has no common factors except 1. So, there LCM is their product i.e 20738606

Least Common Multiple of 2686,7721 with GCF Formula

Least Common Multiple of 2686,7721 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 2686,7721 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(2686,7721) = 1

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

GCF(2686,7721) x common factors =1 x 1 = 1

LCM(2686,7721) = ( 2686 × 7721 ) / 1

LCM(2686,7721) = 20738606 / 1

LCM(2686,7721) = 20738606


Lets's calculate GCF of 20,940

2 20, 940
2 10, 470
5 5, 235
1, 47

∴ So the GCF of the given numbers is 2 x 2 x 5 = 20

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 20738606/20

Therefore the LCM of Fractions 2686/20,7721/940 is 20738606/20
