Least Common Multiple of 72/393,31/680,123/249

Given numbers are 72/393,31/680,123/249

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 72,31,123

Least Common Multiple of Numerators i.e. LCM of 72,31,123 is 91512.

GCF of Denominators means GCF of 393,680,249 as per the given fractions.

GCF of 393,680,249 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 72,31,123

LCM of Fractions 72/393,31/680,123/249 is 91512

3 72, 31, 123
24, 31, 41

∴ So the LCM of the given numbers is 3 x 24 x 31 x 41 = 91512

Least Common Multiple of 72,31,123 with GCF Formula

Least Common Multiple of 72,31,123 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 72,31,123 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,31,123) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(72,31,123) x common factors =1 x 3 = 3

LCM(72,31,123) = ( 72 × 31 × 123 ) / 3

LCM(72,31,123) = 274536 / 3

LCM(72,31,123) = 91512


Lets's calculate GCF of 393,680,249

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 91512/1

Therefore the LCM of Fractions 72/393,31/680,123/249 is 91512
