Least Common Multiple of 977/77,378/28,131/91

Given numbers are 977/77,378/28,131/91

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 977,378,131

Least Common Multiple of Numerators i.e. LCM of 977,378,131 is 48379086.

GCF of Denominators means GCF of 77,28,91 as per the given fractions.

GCF of 77,28,91 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 977,378,131

LCM of Fractions 977/77,378/28,131/91 is 6911298

Given numbers has no common factors except 1. So, there LCM is their product i.e 48379086

Least Common Multiple of 977,378,131 with GCF Formula

Least Common Multiple of 977,378,131 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 977,378,131 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(977,378,131) = 1

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

GCF(977,378,131) x common factors =1 x 1 = 1

LCM(977,378,131) = ( 977 × 378 × 131 ) / 1

LCM(977,378,131) = 48379086 / 1

LCM(977,378,131) = 48379086


Lets's calculate GCF of 77,28,91

7 77, 28, 91
11, 4, 13

∴ So the GCF of the given numbers is 7 = 7

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 48379086/7

Therefore the LCM of Fractions 977/77,378/28,131/91 is 6911298
