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 13,566,831

Least Common Multiple of Numerators i.e. LCM of 13,566,831 is 6114498.

GCF of Denominators means GCF of 831,690,420 as per the given fractions.

GCF of 831,690,420 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 13,566,831

LCM of Fractions 13/831,566/690,831/420 is 2038166

Given numbers has no common factors except 1. So, there LCM is their product i.e 6114498

Least Common Multiple of 13,566,831 with GCF Formula

Least Common Multiple of 13,566,831 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 13,566,831 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,566,831) = 1

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

GCF(13,566,831) x common factors =1 x 1 = 1

LCM(13,566,831) = ( 13 × 566 × 831 ) / 1

LCM(13,566,831) = 6114498 / 1

LCM(13,566,831) = 6114498


Lets's calculate GCF of 831,690,420

3 831, 690, 420
277, 230, 140

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6114498/3

Therefore the LCM of Fractions 13/831,566/690,831/420 is 2038166
