Least Common Multiple of 638/90,784/23,159/34

Given numbers are 638/90,784/23,159/34

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 638,784,159

Least Common Multiple of Numerators i.e. LCM of 638,784,159 is 39765264.

GCF of Denominators means GCF of 90,23,34 as per the given fractions.

GCF of 90,23,34 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 638,784,159

LCM of Fractions 638/90,784/23,159/34 is 39765264

2 638, 784, 159
319, 392, 159

∴ So the LCM of the given numbers is 2 x 319 x 392 x 159 = 39765264

Least Common Multiple of 638,784,159 with GCF Formula

Least Common Multiple of 638,784,159 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 638,784,159 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(638,784,159) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(638,784,159) x common factors =1 x 2 = 2

LCM(638,784,159) = ( 638 × 784 × 159 ) / 2

LCM(638,784,159) = 79530528 / 2

LCM(638,784,159) = 39765264


Lets's calculate GCF of 90,23,34

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 39765264/1

Therefore the LCM of Fractions 638/90,784/23,159/34 is 39765264
