Least Common Multiple of 613/78,537/39,438/57

Given numbers are 613/78,537/39,438/57

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 613,537,438

Least Common Multiple of Numerators i.e. LCM of 613,537,438 is 48060426.

GCF of Denominators means GCF of 78,39,57 as per the given fractions.

GCF of 78,39,57 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 613,537,438

LCM of Fractions 613/78,537/39,438/57 is 16020142

3 613, 537, 438
613, 179, 146

∴ So the LCM of the given numbers is 3 x 613 x 179 x 146 = 48060426

Least Common Multiple of 613,537,438 with GCF Formula

Least Common Multiple of 613,537,438 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 613,537,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(613,537,438) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(613,537,438) x common factors =1 x 3 = 3

LCM(613,537,438) = ( 613 × 537 × 438 ) / 3

LCM(613,537,438) = 144181278 / 3

LCM(613,537,438) = 48060426


Lets's calculate GCF of 78,39,57

3 78, 39, 57
26, 13, 19

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 48060426/3

Therefore the LCM of Fractions 613/78,537/39,438/57 is 16020142
