Least Common Multiple of 388/12,396/13,305/489

Given numbers are 388/12,396/13,305/489

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 388,396,305

Least Common Multiple of Numerators i.e. LCM of 388,396,305 is 11715660.

GCF of Denominators means GCF of 12,13,489 as per the given fractions.

GCF of 12,13,489 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 388,396,305

LCM of Fractions 388/12,396/13,305/489 is 11715660

2 388, 396, 305
2 194, 198, 305
97, 99, 305

∴ So the LCM of the given numbers is 2 x 2 x 97 x 99 x 305 = 11715660

Least Common Multiple of 388,396,305 with GCF Formula

Least Common Multiple of 388,396,305 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 388,396,305 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(388,396,305) = 1

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

GCF(388,396,305) x common factors =1 x 4 = 4

LCM(388,396,305) = ( 388 × 396 × 305 ) / 4

LCM(388,396,305) = 46862640 / 4

LCM(388,396,305) = 11715660


Lets's calculate GCF of 12,13,489

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11715660/1

Therefore the LCM of Fractions 388/12,396/13,305/489 is 11715660
