Least Common Multiple (LCM) of 54/72, 57/86, 27/140 is 513.

LCM(54/72, 57/86, 27/140) = 513

LCM of 54/72, 57/86, 27/140

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 54/72,57/86,27/140

Given numbers are 54/72,57/86,27/140

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 54,57,27

Least Common Multiple of Numerators i.e. LCM of 54,57,27 is 1026.

GCF of Denominators means GCF of 72,86,140 as per the given fractions.

GCF of 72,86,140 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 54,57,27

LCM of Fractions 54/72,57/86,27/140 is 513

3 54, 57, 27
3 18, 19, 9
3 6, 19, 3
2, 19, 1

∴ So the LCM of the given numbers is 3 x 3 x 3 x 2 x 19 x 1 = 1026

Least Common Multiple of 54,57,27 with GCF Formula

Least Common Multiple of 54,57,27 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 54,57,27 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(54,57,27) = 3

common factors(in case of two or more numbers have common factors) = 27

GCF(54,57,27) x common factors =3 x 27 = 81

LCM(54,57,27) = ( 54 × 57 × 27 ) / 81

LCM(54,57,27) = 83106 / 81

LCM(54,57,27) = 1026


Lets's calculate GCF of 72,86,140

2 72, 86, 140
36, 43, 70

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1026/2

Therefore the LCM of Fractions 54/72,57/86,27/140 is 513
