LCM of:

Least Common Multiple of 45/180,75/225,100/270

Given numbers are 45/180,75/225,100/270

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 45,75,100

Least Common Multiple of Numerators i.e. LCM of 45,75,100 is 900.

GCF of Denominators means GCF of 180,225,270 as per the given fractions.

GCF of 180,225,270 is 45 as it is the largest common factor for these numbers.

Lets's calculate LCM of 45,75,100

LCM of Fractions 45/180,75/225,100/270 is 20

3 45, 75, 100
5 15, 25, 100
5 3, 5, 20
3, 1, 4

∴ So the LCM of the given numbers is 3 x 5 x 5 x 3 x 1 x 4 = 900

Least Common Multiple of 45,75,100 with GCF Formula

Least Common Multiple of 45,75,100 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 45,75,100 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,75,100) = 5

common factors(in case of two or more numbers have common factors) = 75

GCF(45,75,100) x common factors =5 x 75 = 375

LCM(45,75,100) = ( 45 × 75 × 100 ) / 375

LCM(45,75,100) = 337500 / 375

LCM(45,75,100) = 900


Lets's calculate GCF of 180,225,270

3 180, 225, 270
3 60, 75, 90
5 20, 25, 30
4, 5, 6

∴ So the GCF of the given numbers is 3 x 3 x 5 = 45

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 900/45

Therefore the LCM of Fractions 45/180,75/225,100/270 is 20
