Least Common Multiple of 78/91,43/45,673/820

Given numbers are 78/91,43/45,673/820

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 78,43,673

Least Common Multiple of Numerators i.e. LCM of 78,43,673 is 2257242.

GCF of Denominators means GCF of 91,45,820 as per the given fractions.

GCF of 91,45,820 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,43,673

LCM of Fractions 78/91,43/45,673/820 is 2257242

Given numbers has no common factors except 1. So, there LCM is their product i.e 2257242

Least Common Multiple of 78,43,673 with GCF Formula

Least Common Multiple of 78,43,673 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 78,43,673 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,43,673) = 1

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

GCF(78,43,673) x common factors =1 x 1 = 1

LCM(78,43,673) = ( 78 × 43 × 673 ) / 1

LCM(78,43,673) = 2257242 / 1

LCM(78,43,673) = 2257242


Lets's calculate GCF of 91,45,820

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2257242/1

Therefore the LCM of Fractions 78/91,43/45,673/820 is 2257242
