Least Common Multiple of 20/70,309/61,323/431

Given numbers are 20/70,309/61,323/431

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 20,309,323

Least Common Multiple of Numerators i.e. LCM of 20,309,323 is 1996140.

GCF of Denominators means GCF of 70,61,431 as per the given fractions.

GCF of 70,61,431 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 20,309,323

LCM of Fractions 20/70,309/61,323/431 is 1996140

Given numbers has no common factors except 1. So, there LCM is their product i.e 1996140

Least Common Multiple of 20,309,323 with GCF Formula

Least Common Multiple of 20,309,323 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 20,309,323 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,309,323) = 1

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

GCF(20,309,323) x common factors =1 x 1 = 1

LCM(20,309,323) = ( 20 × 309 × 323 ) / 1

LCM(20,309,323) = 1996140 / 1

LCM(20,309,323) = 1996140


Lets's calculate GCF of 70,61,431

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1996140/1

Therefore the LCM of Fractions 20/70,309/61,323/431 is 1996140
