Least Common Multiple of 81/243,816/90,960/419

Given numbers are 81/243,816/90,960/419

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 81,816,960

Least Common Multiple of Numerators i.e. LCM of 81,816,960 is 440640.

GCF of Denominators means GCF of 243,90,419 as per the given fractions.

GCF of 243,90,419 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,816,960

LCM of Fractions 81/243,816/90,960/419 is 440640

2 81, 816, 960
2 81, 408, 480
2 81, 204, 240
2 81, 102, 120
3 81, 51, 60
27, 17, 20

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 27 x 17 x 20 = 440640

Least Common Multiple of 81,816,960 with GCF Formula

Least Common Multiple of 81,816,960 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 81,816,960 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,816,960) = 3

common factors(in case of two or more numbers have common factors) = 48

GCF(81,816,960) x common factors =3 x 48 = 144

LCM(81,816,960) = ( 81 × 816 × 960 ) / 144

LCM(81,816,960) = 63452160 / 144

LCM(81,816,960) = 440640


Lets's calculate GCF of 243,90,419

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 440640/1

Therefore the LCM of Fractions 81/243,816/90,960/419 is 440640
