LCM of:

Given numbers are 54/30,90/75,108/180

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 54,90,108

Least Common Multiple of Numerators i.e. LCM of 54,90,108 is 540.

GCF of Denominators means GCF of 30,75,180 as per the given fractions.

GCF of 30,75,180 is 15 as it is the largest common factor for these numbers.

Lets's calculate LCM of 54,90,108

Least Common Multiple (LCM) of 54,90,108 By Common Division

2 54, 90, 108
3 27, 45, 54
3 9, 15, 18
3 3, 5, 6
1, 5, 2

∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 1 x 5 x 2 = 540

Least Common Multiple of 54,90,108 with GCF Formula

Least Common Multiple of 54,90,108 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 54,90,108 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(54,90,108) = 18

common factors(in case of two or more numbers have common factors) = 54

GCF(54,90,108) x common factors =18 x 54 = 972

LCM(54,90,108) = ( 54 × 90 × 108 ) / 972

LCM(54,90,108) = 524880 / 972

LCM(54,90,108) = 540


Lets's calculate GCF of 30,75,180

Greatest Common Factor (GCF) of 30,75,180 By Common Division

3 30, 75, 180
5 10, 25, 60
2, 5, 12

∴ So the GCF of the given numbers is 3 x 5 = 15

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 540/15

Therefore the LCM of Fractions 54/30,90/75,108/180 is 36
