Least Common Multiple of 620/399,4431/243

Given numbers are 620/399,4431/243

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 620,4431

Least Common Multiple of Numerators i.e. LCM of 620,4431 is 2747220.

GCF of Denominators means GCF of 399,243 as per the given fractions.

GCF of 399,243 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 620,4431

LCM of Fractions 620/399,4431/243 is 915740

Given numbers has no common factors except 1. So, there LCM is their product i.e 2747220

Least Common Multiple of 620,4431 with GCF Formula

Least Common Multiple of 620,4431 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 620,4431 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(620,4431) = 1

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

GCF(620,4431) x common factors =1 x 1 = 1

LCM(620,4431) = ( 620 × 4431 ) / 1

LCM(620,4431) = 2747220 / 1

LCM(620,4431) = 2747220


Lets's calculate GCF of 399,243

3 399, 243
133, 81

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2747220/3

Therefore the LCM of Fractions 620/399,4431/243 is 915740
