Least Common Multiple of 640/345,981/290,908/411

Given numbers are 640/345,981/290,908/411

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 640,981,908

Least Common Multiple of Numerators i.e. LCM of 640,981,908 is 142519680.

GCF of Denominators means GCF of 345,290,411 as per the given fractions.

GCF of 345,290,411 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 640,981,908

LCM of Fractions 640/345,981/290,908/411 is 142519680

2 640, 981, 908
2 320, 981, 454
160, 981, 227

∴ So the LCM of the given numbers is 2 x 2 x 160 x 981 x 227 = 142519680

Least Common Multiple of 640,981,908 with GCF Formula

Least Common Multiple of 640,981,908 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 640,981,908 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(640,981,908) = 1

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

GCF(640,981,908) x common factors =1 x 4 = 4

LCM(640,981,908) = ( 640 × 981 × 908 ) / 4

LCM(640,981,908) = 570078720 / 4

LCM(640,981,908) = 142519680


Lets's calculate GCF of 345,290,411

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 142519680/1

Therefore the LCM of Fractions 640/345,981/290,908/411 is 142519680
