LCM of:

Least Common Multiple of 90/21,44/724,831/320

Given numbers are 90/21,44/724,831/320

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 90,44,831

Least Common Multiple of Numerators i.e. LCM of 90,44,831 is 548460.

GCF of Denominators means GCF of 21,724,320 as per the given fractions.

GCF of 21,724,320 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 90,44,831

LCM of Fractions 90/21,44/724,831/320 is 548460

2 90, 44, 831
3 45, 22, 831
15, 22, 277

∴ So the LCM of the given numbers is 2 x 3 x 15 x 22 x 277 = 548460

Least Common Multiple of 90,44,831 with GCF Formula

Least Common Multiple of 90,44,831 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 90,44,831 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,44,831) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(90,44,831) x common factors =1 x 6 = 6

LCM(90,44,831) = ( 90 × 44 × 831 ) / 6

LCM(90,44,831) = 3290760 / 6

LCM(90,44,831) = 548460


Lets's calculate GCF of 21,724,320

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 548460/1

Therefore the LCM of Fractions 90/21,44/724,831/320 is 548460
