LCM(65/75, 30/40, 50/60) = 390

LCM of 65/75, 30/40, 50/60

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Given numbers are 65/75,30/40,50/60

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 65,30,50

Least Common Multiple of Numerators i.e. LCM of 65,30,50 is 1950.

GCF of Denominators means GCF of 75,40,60 as per the given fractions.

GCF of 75,40,60 is 5 as it is the largest common factor for these numbers.

Lets's calculate LCM of 65,30,50

Least Common Multiple (LCM) of 65,30,50 By Common Division

2 65, 30, 50
5 65, 15, 25
13, 3, 5

∴ So the LCM of the given numbers is 2 x 5 x 13 x 3 x 5 = 1950

Least Common Multiple of 65,30,50 with GCF Formula

Least Common Multiple of 65,30,50 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 65,30,50 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(65,30,50) = 5

common factors(in case of two or more numbers have common factors) = 10

GCF(65,30,50) x common factors =5 x 10 = 50

LCM(65,30,50) = ( 65 × 30 × 50 ) / 50

LCM(65,30,50) = 97500 / 50

LCM(65,30,50) = 1950


Lets's calculate GCF of 75,40,60

Greatest Common Factor (GCF) of 75,40,60 By Common Division

5 75, 40, 60
15, 8, 12

∴ So the GCF of the given numbers is 5 = 5

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1950/5

Therefore the LCM of Fractions 65/75,30/40,50/60 is 390
