LCM of:

Least Common Multiple of 243/889,840/431

Given numbers are 243/889,840/431

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 243,840

Least Common Multiple of Numerators i.e. LCM of 243,840 is 68040.

GCF of Denominators means GCF of 889,431 as per the given fractions.

GCF of 889,431 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 243,840

LCM of Fractions 243/889,840/431 is 68040

3 243, 840
81, 280

∴ So the LCM of the given numbers is 3 x 81 x 280 = 68040

Least Common Multiple of 243,840 with GCF Formula

Least Common Multiple of 243,840 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 243,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(243,840) = 3

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

GCF(243,840) x common factors =3 x 1 = 3

LCM(243,840) = ( 243 × 840 ) / 3

LCM(243,840) = 204120 / 3

LCM(243,840) = 68040


Lets's calculate GCF of 889,431

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 68040/1

Therefore the LCM of Fractions 243/889,840/431 is 68040
