Given numbers are 642/40,862/57,794/149

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 642,862,794

Least Common Multiple of Numerators i.e. LCM of 642,862,794 is 109850694.

GCF of Denominators means GCF of 40,57,149 as per the given fractions.

GCF of 40,57,149 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 642,862,794

LCM of Fractions 642/40,862/57,794/149 is 109850694

2 642, 862, 794
321, 431, 397

∴ So the LCM of the given numbers is 2 x 321 x 431 x 397 = 109850694

Least Common Multiple of 642,862,794 with GCF Formula

Least Common Multiple of 642,862,794 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 642,862,794 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(642,862,794) = 2

common factors(in case of two or more numbers have common factors) = 2

GCF(642,862,794) x common factors =2 x 2 = 4

LCM(642,862,794) = ( 642 × 862 × 794 ) / 4

LCM(642,862,794) = 439402776 / 4

LCM(642,862,794) = 109850694


Lets's calculate GCF of 40,57,149

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 109850694/1

Therefore the LCM of Fractions 642/40,862/57,794/149 is 109850694
