Least Common Multiple of 813/20,128/82,316/561

Given numbers are 813/20,128/82,316/561

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 813,128,316

Least Common Multiple of Numerators i.e. LCM of 813,128,316 is 8221056.

GCF of Denominators means GCF of 20,82,561 as per the given fractions.

GCF of 20,82,561 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 813,128,316

LCM of Fractions 813/20,128/82,316/561 is 8221056

2 813, 128, 316
2 813, 64, 158
813, 32, 79

∴ So the LCM of the given numbers is 2 x 2 x 813 x 32 x 79 = 8221056

Least Common Multiple of 813,128,316 with GCF Formula

Least Common Multiple of 813,128,316 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 813,128,316 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(813,128,316) = 1

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

GCF(813,128,316) x common factors =1 x 4 = 4

LCM(813,128,316) = ( 813 × 128 × 316 ) / 4

LCM(813,128,316) = 32884224 / 4

LCM(813,128,316) = 8221056


Lets's calculate GCF of 20,82,561

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 8221056/1

Therefore the LCM of Fractions 813/20,128/82,316/561 is 8221056
