GCF of Denominators means GCF of 72,691 as per the given fractions.

GCF of 72,691 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 1398,7111

LCM of Fractions 1398/72,7111/691 is 9941178

Given numbers has no common factors except 1. So, there LCM is their product i.e 9941178

Least Common Multiple of 1398,7111 with GCF Formula

Least Common Multiple of 1398,7111 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 1398,7111 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1398,7111) = 1

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

GCF(1398,7111) x common factors =1 x 1 = 1

LCM(1398,7111) = ( 1398 × 7111 ) / 1

LCM(1398,7111) = 9941178 / 1

LCM(1398,7111) = 9941178


Lets's calculate GCF of 72,691

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9941178/1

Therefore the LCM of Fractions 1398/72,7111/691 is 9941178
