Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 39/491,13/638

Given numbers are 39/491,13/638

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 39,13

Least Common Multiple of Numerators i.e. LCM of 39,13 is 39.

GCF of Denominators means GCF of 491,638 as per the given fractions.

GCF of 491,638 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 39,13

LCM of Fractions 39/491,13/638 is 39

13 39, 13
3, 1

∴ So the LCM of the given numbers is 13 x 3 x 1 = 39

Least Common Multiple of 39,13 with GCF Formula

Least Common Multiple of 39,13 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 39,13 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,13) = 13

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

GCF(39,13) x common factors =13 x 1 = 13

LCM(39,13) = ( 39 × 13 ) / 13

LCM(39,13) = 507 / 13

LCM(39,13) = 39


Lets's calculate GCF of 491,638

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 39/1

Therefore the LCM of Fractions 39/491,13/638 is 39
