LCM of 3/72, 28/32, 139/14

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 3/72,28/32,139/14

Given numbers are 3/72,28/32,139/14

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 3,28,139

Least Common Multiple of Numerators i.e. LCM of 3,28,139 is 11676.

GCF of Denominators means GCF of 72,32,14 as per the given fractions.

GCF of 72,32,14 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 3,28,139

LCM of Fractions 3/72,28/32,139/14 is 5838

Given numbers has no common factors except 1. So, there LCM is their product i.e 11676

Least Common Multiple of 3,28,139 with GCF Formula

Least Common Multiple of 3,28,139 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 3,28,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(3,28,139) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(3,28,139) x common factors =1 x 1 = 1

LCM(3,28,139) = ( 3 × 28 × 139 ) / 1

LCM(3,28,139) = 11676 / 1

LCM(3,28,139) = 11676


Lets's calculate GCF of 72,32,14

2 72, 32, 14
36, 16, 7

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11676/2

Therefore the LCM of Fractions 3/72,28/32,139/14 is 5838
