Least Common Multiple of 398/390,844/724

Given numbers are 398/390,844/724

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 398,844

Least Common Multiple of Numerators i.e. LCM of 398,844 is 167956.

GCF of Denominators means GCF of 390,724 as per the given fractions.

GCF of 390,724 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 398,844

LCM of Fractions 398/390,844/724 is 83978

2 398, 844
199, 422

∴ So the LCM of the given numbers is 2 x 199 x 422 = 167956

Least Common Multiple of 398,844 with GCF Formula

Least Common Multiple of 398,844 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 398,844 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(398,844) = 2

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

GCF(398,844) x common factors =2 x 1 = 2

LCM(398,844) = ( 398 × 844 ) / 2

LCM(398,844) = 335912 / 2

LCM(398,844) = 167956


Lets's calculate GCF of 390,724

2 390, 724
195, 362

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 167956/2

Therefore the LCM of Fractions 398/390,844/724 is 83978
