Least Common Multiple of 12/638,411/54,390/783

Given numbers are 12/638,411/54,390/783

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 12,411,390

Least Common Multiple of Numerators i.e. LCM of 12,411,390 is 106860.

GCF of Denominators means GCF of 638,54,783 as per the given fractions.

GCF of 638,54,783 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 12,411,390

LCM of Fractions 12/638,411/54,390/783 is 106860

2 12, 411, 390
3 6, 411, 195
2, 137, 65

∴ So the LCM of the given numbers is 2 x 3 x 2 x 137 x 65 = 106860

Least Common Multiple of 12,411,390 with GCF Formula

Least Common Multiple of 12,411,390 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 12,411,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,411,390) = 3

common factors(in case of two or more numbers have common factors) = 6

GCF(12,411,390) x common factors =3 x 6 = 18

LCM(12,411,390) = ( 12 × 411 × 390 ) / 18

LCM(12,411,390) = 1923480 / 18

LCM(12,411,390) = 106860


Lets's calculate GCF of 638,54,783

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 106860/1

Therefore the LCM of Fractions 12/638,411/54,390/783 is 106860
