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 1997,1597

Least Common Multiple of Numerators i.e. LCM of 1997,1597 is 3189209.

GCF of Denominators means GCF of 27,781 as per the given fractions.

GCF of 27,781 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 1997,1597

LCM of Fractions 1997/27,1597/781 is 3189209

Given numbers has no common factors except 1. So, there LCM is their product i.e 3189209

Least Common Multiple of 1997,1597 with GCF Formula

Least Common Multiple of 1997,1597 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 1997,1597 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1997,1597) = 1

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

GCF(1997,1597) x common factors =1 x 1 = 1

LCM(1997,1597) = ( 1997 × 1597 ) / 1

LCM(1997,1597) = 3189209 / 1

LCM(1997,1597) = 3189209


Lets's calculate GCF of 27,781

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3189209/1

Therefore the LCM of Fractions 1997/27,1597/781 is 3189209
