LCM of:

Least Common Multiple of 142/78,478/646

Given numbers are 142/78,478/646

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 142,478

Least Common Multiple of Numerators i.e. LCM of 142,478 is 33938.

GCF of Denominators means GCF of 78,646 as per the given fractions.

GCF of 78,646 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 142,478

LCM of Fractions 142/78,478/646 is 16969

2 142, 478
71, 239

∴ So the LCM of the given numbers is 2 x 71 x 239 = 33938

Least Common Multiple of 142,478 with GCF Formula

Least Common Multiple of 142,478 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 142,478 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(142,478) = 2

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

GCF(142,478) x common factors =2 x 1 = 2

LCM(142,478) = ( 142 × 478 ) / 2

LCM(142,478) = 67876 / 2

LCM(142,478) = 33938


Lets's calculate GCF of 78,646

2 78, 646
39, 323

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 33938/2

Therefore the LCM of Fractions 142/78,478/646 is 16969
