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 1990,2049

Least Common Multiple of Numerators i.e. LCM of 1990,2049 is 4077510.

GCF of Denominators means GCF of 20,617 as per the given fractions.

GCF of 20,617 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 1990,2049

LCM of Fractions 1990/20,2049/617 is 4077510

Given numbers has no common factors except 1. So, there LCM is their product i.e 4077510

Least Common Multiple of 1990,2049 with GCF Formula

Least Common Multiple of 1990,2049 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 1990,2049 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1990,2049) = 1

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

GCF(1990,2049) x common factors =1 x 1 = 1

LCM(1990,2049) = ( 1990 × 2049 ) / 1

LCM(1990,2049) = 4077510 / 1

LCM(1990,2049) = 4077510


Lets's calculate GCF of 20,617

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4077510/1

Therefore the LCM of Fractions 1990/20,2049/617 is 4077510
