Least Common Multiple of 40/515,556/690,831/645

Given numbers are 40/515,556/690,831/645

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 40,556,831

Least Common Multiple of Numerators i.e. LCM of 40,556,831 is 4620360.

GCF of Denominators means GCF of 515,690,645 as per the given fractions.

GCF of 515,690,645 is 5 as it is the largest common factor for these numbers.

Lets's calculate LCM of 40,556,831

LCM of Fractions 40/515,556/690,831/645 is 924072

2 40, 556, 831
2 20, 278, 831
10, 139, 831

∴ So the LCM of the given numbers is 2 x 2 x 10 x 139 x 831 = 4620360

Least Common Multiple of 40,556,831 with GCF Formula

Least Common Multiple of 40,556,831 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 40,556,831 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,556,831) = 1

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

GCF(40,556,831) x common factors =1 x 4 = 4

LCM(40,556,831) = ( 40 × 556 × 831 ) / 4

LCM(40,556,831) = 18481440 / 4

LCM(40,556,831) = 4620360


Lets's calculate GCF of 515,690,645

5 515, 690, 645
103, 138, 129

∴ So the GCF of the given numbers is 5 = 5

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4620360/5

Therefore the LCM of Fractions 40/515,556/690,831/645 is 924072
