Least Common Multiple of 81/347,21/378,841/469

Given numbers are 81/347,21/378,841/469

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 81,21,841

Least Common Multiple of Numerators i.e. LCM of 81,21,841 is 476847.

GCF of Denominators means GCF of 347,378,469 as per the given fractions.

GCF of 347,378,469 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,21,841

LCM of Fractions 81/347,21/378,841/469 is 476847

3 81, 21, 841
27, 7, 841

∴ So the LCM of the given numbers is 3 x 27 x 7 x 841 = 476847

Least Common Multiple of 81,21,841 with GCF Formula

Least Common Multiple of 81,21,841 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 81,21,841 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,21,841) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(81,21,841) x common factors =1 x 3 = 3

LCM(81,21,841) = ( 81 × 21 × 841 ) / 3

LCM(81,21,841) = 1430541 / 3

LCM(81,21,841) = 476847


Lets's calculate GCF of 347,378,469

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 476847/1

Therefore the LCM of Fractions 81/347,21/378,841/469 is 476847
