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 991,7861

Least Common Multiple of Numerators i.e. LCM of 991,7861 is 7790251.

GCF of Denominators means GCF of 81,531 as per the given fractions.

GCF of 81,531 is 9 as it is the largest common factor for these numbers.

Lets's calculate LCM of 991,7861

LCM of Fractions 991/81,7861/531 is 7790251/9

Given numbers has no common factors except 1. So, there LCM is their product i.e 7790251

Least Common Multiple of 991,7861 with GCF Formula

Least Common Multiple of 991,7861 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 991,7861 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(991,7861) = 1

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

GCF(991,7861) x common factors =1 x 1 = 1

LCM(991,7861) = ( 991 × 7861 ) / 1

LCM(991,7861) = 7790251 / 1

LCM(991,7861) = 7790251


Lets's calculate GCF of 81,531

3 81, 531
3 27, 177
9, 59

∴ So the GCF of the given numbers is 3 x 3 = 9

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7790251/9

Therefore the LCM of Fractions 991/81,7861/531 is 7790251/9
