Least Common Multiple (LCM) of 36/81, 60/15, 72/855 is 120.

LCM(36/81, 60/15, 72/855) = 120

LCM of 36/81, 60/15, 72/855

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 36/81,60/15,72/855

Given numbers are 36/81,60/15,72/855

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 36,60,72

Least Common Multiple of Numerators i.e. LCM of 36,60,72 is 360.

GCF of Denominators means GCF of 81,15,855 as per the given fractions.

GCF of 81,15,855 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 36,60,72

LCM of Fractions 36/81,60/15,72/855 is 120

2 36, 60, 72
2 18, 30, 36
3 9, 15, 18
3 3, 5, 6
1, 5, 2

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 5 x 2 = 360

Least Common Multiple of 36,60,72 with GCF Formula

Least Common Multiple of 36,60,72 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 36,60,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(36,60,72) = 12

common factors(in case of two or more numbers have common factors) = 36

GCF(36,60,72) x common factors =12 x 36 = 432

LCM(36,60,72) = ( 36 × 60 × 72 ) / 432

LCM(36,60,72) = 155520 / 432

LCM(36,60,72) = 360


Lets's calculate GCF of 81,15,855

3 81, 15, 855
27, 5, 285

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 360/3

Therefore the LCM of Fractions 36/81,60/15,72/855 is 120
