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 51,394,979

Least Common Multiple of Numerators i.e. LCM of 51,394,979 is 19672026.

GCF of Denominators means GCF of 390,489,432 as per the given fractions.

GCF of 390,489,432 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 51,394,979

LCM of Fractions 51/390,394/489,979/432 is 6557342

Given numbers has no common factors except 1. So, there LCM is their product i.e 19672026

Least Common Multiple of 51,394,979 with GCF Formula

Least Common Multiple of 51,394,979 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 51,394,979 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,394,979) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(51,394,979) x common factors =1 x 1 = 1

LCM(51,394,979) = ( 51 × 394 × 979 ) / 1

LCM(51,394,979) = 19672026 / 1

LCM(51,394,979) = 19672026


Lets's calculate GCF of 390,489,432

3 390, 489, 432
130, 163, 144

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 19672026/3

Therefore the LCM of Fractions 51/390,394/489,979/432 is 6557342
