LCM of:

Least Common Multiple of 76/47,90/81,13/430

Given numbers are 76/47,90/81,13/430

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 76,90,13

Least Common Multiple of Numerators i.e. LCM of 76,90,13 is 44460.

GCF of Denominators means GCF of 47,81,430 as per the given fractions.

GCF of 47,81,430 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 76,90,13

LCM of Fractions 76/47,90/81,13/430 is 44460

2 76, 90, 13
38, 45, 13

∴ So the LCM of the given numbers is 2 x 38 x 45 x 13 = 44460

Least Common Multiple of 76,90,13 with GCF Formula

Least Common Multiple of 76,90,13 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 76,90,13 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(76,90,13) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(76,90,13) x common factors =1 x 2 = 2

LCM(76,90,13) = ( 76 × 90 × 13 ) / 2

LCM(76,90,13) = 88920 / 2

LCM(76,90,13) = 44460


Lets's calculate GCF of 47,81,430

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 44460/1

Therefore the LCM of Fractions 76/47,90/81,13/430 is 44460
