Least Common Multiple of 39/81,13/84,571/289

Given numbers are 39/81,13/84,571/289

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 39,13,571

Least Common Multiple of Numerators i.e. LCM of 39,13,571 is 22269.

GCF of Denominators means GCF of 81,84,289 as per the given fractions.

GCF of 81,84,289 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 39,13,571

LCM of Fractions 39/81,13/84,571/289 is 22269

13 39, 13, 571
3, 1, 571

∴ So the LCM of the given numbers is 13 x 3 x 1 x 571 = 22269

Least Common Multiple of 39,13,571 with GCF Formula

Least Common Multiple of 39,13,571 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 39,13,571 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,13,571) = 1

common factors(in case of two or more numbers have common factors) = 13

GCF(39,13,571) x common factors =1 x 13 = 13

LCM(39,13,571) = ( 39 × 13 × 571 ) / 13

LCM(39,13,571) = 289497 / 13

LCM(39,13,571) = 22269


Lets's calculate GCF of 81,84,289

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 22269/1

Therefore the LCM of Fractions 39/81,13/84,571/289 is 22269
