Least Common Multiple (LCM) of 12/42, 48/18, 80/333 is 80.

LCM(12/42, 48/18, 80/333) = 80

LCM of 12/42, 48/18, 80/333

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 12/42,48/18,80/333

Given numbers are 12/42,48/18,80/333

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 12,48,80

Least Common Multiple of Numerators i.e. LCM of 12,48,80 is 240.

GCF of Denominators means GCF of 42,18,333 as per the given fractions.

GCF of 42,18,333 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 12,48,80

LCM of Fractions 12/42,48/18,80/333 is 80

2 12, 48, 80
2 6, 24, 40
2 3, 12, 20
2 3, 6, 10
3 3, 3, 5
1, 1, 5

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 1 x 1 x 5 = 240

Least Common Multiple of 12,48,80 with GCF Formula

Least Common Multiple of 12,48,80 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 12,48,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,48,80) = 4

common factors(in case of two or more numbers have common factors) = 48

GCF(12,48,80) x common factors =4 x 48 = 192

LCM(12,48,80) = ( 12 × 48 × 80 ) / 192

LCM(12,48,80) = 46080 / 192

LCM(12,48,80) = 240


Lets's calculate GCF of 42,18,333

3 42, 18, 333
14, 6, 111

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 240/3

Therefore the LCM of Fractions 12/42,48/18,80/333 is 80
