LCM of:

Least Common Multiple of 621/20,743/438

Given numbers are 621/20,743/438

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 621,743

Least Common Multiple of Numerators i.e. LCM of 621,743 is 461403.

GCF of Denominators means GCF of 20,438 as per the given fractions.

GCF of 20,438 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 621,743

LCM of Fractions 621/20,743/438 is 461403/2

Given numbers has no common factors except 1. So, there LCM is their product i.e 461403

Least Common Multiple of 621,743 with GCF Formula

Least Common Multiple of 621,743 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 621,743 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(621,743) = 1

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

GCF(621,743) x common factors =1 x 1 = 1

LCM(621,743) = ( 621 × 743 ) / 1

LCM(621,743) = 461403 / 1

LCM(621,743) = 461403


Lets's calculate GCF of 20,438

2 20, 438
10, 219

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 461403/2

Therefore the LCM of Fractions 621/20,743/438 is 461403/2
