Least Common Multiple of 81/44,778/21,389/318

Given numbers are 81/44,778/21,389/318

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 81,778,389

Least Common Multiple of Numerators i.e. LCM of 81,778,389 is 63018.

GCF of Denominators means GCF of 44,21,318 as per the given fractions.

GCF of 44,21,318 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,778,389

LCM of Fractions 81/44,778/21,389/318 is 63018

389 81, 778, 389
81, 2, 1

∴ So the LCM of the given numbers is 389 x 81 x 2 x 1 = 63018

Least Common Multiple of 81,778,389 with GCF Formula

Least Common Multiple of 81,778,389 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 81,778,389 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,778,389) = 1

common factors(in case of two or more numbers have common factors) = 389

GCF(81,778,389) x common factors =1 x 389 = 389

LCM(81,778,389) = ( 81 × 778 × 389 ) / 389

LCM(81,778,389) = 24514002 / 389

LCM(81,778,389) = 63018


Lets's calculate GCF of 44,21,318

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 63018/1

Therefore the LCM of Fractions 81/44,778/21,389/318 is 63018
