Given numbers are 40/428,278/897,956/742

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 40,278,956

Least Common Multiple of Numerators i.e. LCM of 40,278,956 is 1328840.

GCF of Denominators means GCF of 428,897,742 as per the given fractions.

GCF of 428,897,742 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 40,278,956

LCM of Fractions 40/428,278/897,956/742 is 1328840

2 40, 278, 956
2 20, 139, 478
10, 139, 239

∴ So the LCM of the given numbers is 2 x 2 x 10 x 139 x 239 = 1328840

Least Common Multiple of 40,278,956 with GCF Formula

Least Common Multiple of 40,278,956 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 40,278,956 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,278,956) = 2

common factors(in case of two or more numbers have common factors) = 4

GCF(40,278,956) x common factors =2 x 4 = 8

LCM(40,278,956) = ( 40 × 278 × 956 ) / 8

LCM(40,278,956) = 10630720 / 8

LCM(40,278,956) = 1328840


Lets's calculate GCF of 428,897,742

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1328840/1

Therefore the LCM of Fractions 40/428,278/897,956/742 is 1328840
