Least Common Multiple of 19/75,861/56,287/243

Given numbers are 19/75,861/56,287/243

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 19,861,287

Least Common Multiple of Numerators i.e. LCM of 19,861,287 is 16359.

GCF of Denominators means GCF of 75,56,243 as per the given fractions.

GCF of 75,56,243 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 19,861,287

LCM of Fractions 19/75,861/56,287/243 is 16359

7 19, 861, 287
41 19, 123, 41
19, 3, 1

∴ So the LCM of the given numbers is 7 x 41 x 19 x 3 x 1 = 16359

Least Common Multiple of 19,861,287 with GCF Formula

Least Common Multiple of 19,861,287 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 19,861,287 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(19,861,287) = 1

common factors(in case of two or more numbers have common factors) = 287

GCF(19,861,287) x common factors =1 x 287 = 287

LCM(19,861,287) = ( 19 × 861 × 287 ) / 287

LCM(19,861,287) = 4695033 / 287

LCM(19,861,287) = 16359


Lets's calculate GCF of 75,56,243

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 16359/1

Therefore the LCM of Fractions 19/75,861/56,287/243 is 16359
