Least Common Multiple of 40/31,643/40,327/788

Given numbers are 40/31,643/40,327/788

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 40,643,327

Least Common Multiple of Numerators i.e. LCM of 40,643,327 is 8410440.

GCF of Denominators means GCF of 31,40,788 as per the given fractions.

GCF of 31,40,788 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 40,643,327

LCM of Fractions 40/31,643/40,327/788 is 8410440

Given numbers has no common factors except 1. So, there LCM is their product i.e 8410440

Least Common Multiple of 40,643,327 with GCF Formula

Least Common Multiple of 40,643,327 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 40,643,327 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,643,327) = 1

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

GCF(40,643,327) x common factors =1 x 1 = 1

LCM(40,643,327) = ( 40 × 643 × 327 ) / 1

LCM(40,643,327) = 8410440 / 1

LCM(40,643,327) = 8410440


Lets's calculate GCF of 31,40,788

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 8410440/1

Therefore the LCM of Fractions 40/31,643/40,327/788 is 8410440
