Least Common Multiple of 91/43,731/13,261/138

Given numbers are 91/43,731/13,261/138

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 91,731,261

Least Common Multiple of Numerators i.e. LCM of 91,731,261 is 17361981.

GCF of Denominators means GCF of 43,13,138 as per the given fractions.

GCF of 43,13,138 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 91,731,261

LCM of Fractions 91/43,731/13,261/138 is 17361981

Given numbers has no common factors except 1. So, there LCM is their product i.e 17361981

Least Common Multiple of 91,731,261 with GCF Formula

Least Common Multiple of 91,731,261 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 91,731,261 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(91,731,261) = 1

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

GCF(91,731,261) x common factors =1 x 1 = 1

LCM(91,731,261) = ( 91 × 731 × 261 ) / 1

LCM(91,731,261) = 17361981 / 1

LCM(91,731,261) = 17361981


Lets's calculate GCF of 43,13,138

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 17361981/1

Therefore the LCM of Fractions 91/43,731/13,261/138 is 17361981
