Least Common Multiple of 91/49,768/90,249/686

Given numbers are 91/49,768/90,249/686

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 91,768,249

Least Common Multiple of Numerators i.e. LCM of 91,768,249 is 5800704.

GCF of Denominators means GCF of 49,90,686 as per the given fractions.

GCF of 49,90,686 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 91,768,249

LCM of Fractions 91/49,768/90,249/686 is 5800704

3 91, 768, 249
91, 256, 83

∴ So the LCM of the given numbers is 3 x 91 x 256 x 83 = 5800704

Least Common Multiple of 91,768,249 with GCF Formula

Least Common Multiple of 91,768,249 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 91,768,249 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(91,768,249) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(91,768,249) x common factors =1 x 3 = 3

LCM(91,768,249) = ( 91 × 768 × 249 ) / 3

LCM(91,768,249) = 17402112 / 3

LCM(91,768,249) = 5800704


Lets's calculate GCF of 49,90,686

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5800704/1

Therefore the LCM of Fractions 91/49,768/90,249/686 is 5800704
