LCM of:

Least Common Multiple of 72/29,56/31,368/81

Given numbers are 72/29,56/31,368/81

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 72,56,368

Least Common Multiple of Numerators i.e. LCM of 72,56,368 is 23184.

GCF of Denominators means GCF of 29,31,81 as per the given fractions.

GCF of 29,31,81 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 72,56,368

LCM of Fractions 72/29,56/31,368/81 is 23184

2 72, 56, 368
2 36, 28, 184
2 18, 14, 92
9, 7, 46

∴ So the LCM of the given numbers is 2 x 2 x 2 x 9 x 7 x 46 = 23184

Least Common Multiple of 72,56,368 with GCF Formula

Least Common Multiple of 72,56,368 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 72,56,368 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,56,368) = 8

common factors(in case of two or more numbers have common factors) = 8

GCF(72,56,368) x common factors =8 x 8 = 64

LCM(72,56,368) = ( 72 × 56 × 368 ) / 64

LCM(72,56,368) = 1483776 / 64

LCM(72,56,368) = 23184


Lets's calculate GCF of 29,31,81

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 23184/1

Therefore the LCM of Fractions 72/29,56/31,368/81 is 23184
