Least Common Multiple of 31/42,43/69,62/339

Given numbers are 31/42,43/69,62/339

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 31,43,62

Least Common Multiple of Numerators i.e. LCM of 31,43,62 is 2666.

GCF of Denominators means GCF of 42,69,339 as per the given fractions.

GCF of 42,69,339 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 31,43,62

LCM of Fractions 31/42,43/69,62/339 is 2666/3

31 31, 43, 62
1, 43, 2

∴ So the LCM of the given numbers is 31 x 1 x 43 x 2 = 2666

Least Common Multiple of 31,43,62 with GCF Formula

Least Common Multiple of 31,43,62 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 31,43,62 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,43,62) = 1

common factors(in case of two or more numbers have common factors) = 31

GCF(31,43,62) x common factors =1 x 31 = 31

LCM(31,43,62) = ( 31 × 43 × 62 ) / 31

LCM(31,43,62) = 82646 / 31

LCM(31,43,62) = 2666


Lets's calculate GCF of 42,69,339

3 42, 69, 339
14, 23, 113

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2666/3

Therefore the LCM of Fractions 31/42,43/69,62/339 is 2666/3
