Least Common Multiple of 81/70,831/66,431/180

Given numbers are 81/70,831/66,431/180

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 81,831,431

Least Common Multiple of Numerators i.e. LCM of 81,831,431 is 9670347.

GCF of Denominators means GCF of 70,66,180 as per the given fractions.

GCF of 70,66,180 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,831,431

LCM of Fractions 81/70,831/66,431/180 is 9670347/2

3 81, 831, 431
27, 277, 431

∴ So the LCM of the given numbers is 3 x 27 x 277 x 431 = 9670347

Least Common Multiple of 81,831,431 with GCF Formula

Least Common Multiple of 81,831,431 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 81,831,431 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,831,431) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(81,831,431) x common factors =1 x 3 = 3

LCM(81,831,431) = ( 81 × 831 × 431 ) / 3

LCM(81,831,431) = 29011041 / 3

LCM(81,831,431) = 9670347


Lets's calculate GCF of 70,66,180

2 70, 66, 180
35, 33, 90

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9670347/2

Therefore the LCM of Fractions 81/70,831/66,431/180 is 9670347/2
