Least Common Multiple of 128/54,938/99,391/441

Given numbers are 128/54,938/99,391/441

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 128,938,391

Least Common Multiple of Numerators i.e. LCM of 128,938,391 is 23472512.

GCF of Denominators means GCF of 54,99,441 as per the given fractions.

GCF of 54,99,441 is 9 as it is the largest common factor for these numbers.

Lets's calculate LCM of 128,938,391

LCM of Fractions 128/54,938/99,391/441 is 23472512/9

2 128, 938, 391
64, 469, 391

∴ So the LCM of the given numbers is 2 x 64 x 469 x 391 = 23472512

Least Common Multiple of 128,938,391 with GCF Formula

Least Common Multiple of 128,938,391 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 128,938,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(128,938,391) = 1

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

GCF(128,938,391) x common factors =1 x 2 = 2

LCM(128,938,391) = ( 128 × 938 × 391 ) / 2

LCM(128,938,391) = 46945024 / 2

LCM(128,938,391) = 23472512


Lets's calculate GCF of 54,99,441

3 54, 99, 441
3 18, 33, 147
6, 11, 49

∴ So the GCF of the given numbers is 3 x 3 = 9

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 23472512/9

Therefore the LCM of Fractions 128/54,938/99,391/441 is 23472512/9
