Least Common Multiple of 12/48,38/36,331/20

Given numbers are 12/48,38/36,331/20

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 12,38,331

Least Common Multiple of Numerators i.e. LCM of 12,38,331 is 75468.

GCF of Denominators means GCF of 48,36,20 as per the given fractions.

GCF of 48,36,20 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 12,38,331

LCM of Fractions 12/48,38/36,331/20 is 18867

2 12, 38, 331
6, 19, 331

∴ So the LCM of the given numbers is 2 x 6 x 19 x 331 = 75468

Least Common Multiple of 12,38,331 with GCF Formula

Least Common Multiple of 12,38,331 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 12,38,331 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,38,331) = 1

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

GCF(12,38,331) x common factors =1 x 2 = 2

LCM(12,38,331) = ( 12 × 38 × 331 ) / 2

LCM(12,38,331) = 150936 / 2

LCM(12,38,331) = 75468


Lets's calculate GCF of 48,36,20

2 48, 36, 20
2 24, 18, 10
12, 9, 5

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 75468/4

Therefore the LCM of Fractions 12/48,38/36,331/20 is 18867
