Least Common Multiple of 43/80,81/13,20/85,97/815

Given numbers are 43/80,81/13,20/85,97/815

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 43,81,20,97

Least Common Multiple of Numerators i.e. LCM of 43,81,20,97 is 6757020.

GCF of Denominators means GCF of 80,13,85,815 as per the given fractions.

GCF of 80,13,85,815 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 43,81,20,97

LCM of Fractions 43/80,81/13,20/85,97/815 is 6757020

Given numbers has no common factors except 1. So, there LCM is their product i.e 6757020

Least Common Multiple of 43,81,20,97 with GCF Formula

Least Common Multiple of 43,81,20,97 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 43,81,20,97 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(43,81,20,97) = 1

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

GCF(43,81,20,97) x common factors =1 x 1 = 1

LCM(43,81,20,97) = ( 43 × 81 × 20 × 97 ) / 1

LCM(43,81,20,97) = 6757020 / 1

LCM(43,81,20,97) = 6757020


Lets's calculate GCF of 80,13,85,815

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6757020/1

Therefore the LCM of Fractions 43/80,81/13,20/85,97/815 is 6757020
