Least Common Multiple of 7/18,921/65,634/77

Given numbers are 7/18,921/65,634/77

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 7,921,634

Least Common Multiple of Numerators i.e. LCM of 7,921,634 is 4087398.

GCF of Denominators means GCF of 18,65,77 as per the given fractions.

GCF of 18,65,77 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 7,921,634

LCM of Fractions 7/18,921/65,634/77 is 4087398

Given numbers has no common factors except 1. So, there LCM is their product i.e 4087398

Least Common Multiple of 7,921,634 with GCF Formula

Least Common Multiple of 7,921,634 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 7,921,634 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7,921,634) = 1

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

GCF(7,921,634) x common factors =1 x 1 = 1

LCM(7,921,634) = ( 7 × 921 × 634 ) / 1

LCM(7,921,634) = 4087398 / 1

LCM(7,921,634) = 4087398


Lets's calculate GCF of 18,65,77

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4087398/1

Therefore the LCM of Fractions 7/18,921/65,634/77 is 4087398
