Least Common Multiple of 42/791,278/680,921/136

Given numbers are 42/791,278/680,921/136

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 42,278,921

Least Common Multiple of Numerators i.e. LCM of 42,278,921 is 1792266.

GCF of Denominators means GCF of 791,680,136 as per the given fractions.

GCF of 791,680,136 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,278,921

LCM of Fractions 42/791,278/680,921/136 is 1792266

2 42, 278, 921
3 21, 139, 921
7, 139, 307

∴ So the LCM of the given numbers is 2 x 3 x 7 x 139 x 307 = 1792266

Least Common Multiple of 42,278,921 with GCF Formula

Least Common Multiple of 42,278,921 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 42,278,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,278,921) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(42,278,921) x common factors =1 x 6 = 6

LCM(42,278,921) = ( 42 × 278 × 921 ) / 6

LCM(42,278,921) = 10753596 / 6

LCM(42,278,921) = 1792266


Lets's calculate GCF of 791,680,136

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1792266/1

Therefore the LCM of Fractions 42/791,278/680,921/136 is 1792266
