LCM of 3/28, 57/49, 125/45

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 3/28,57/49,125/45

Given numbers are 3/28,57/49,125/45

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 3,57,125

Least Common Multiple of Numerators i.e. LCM of 3,57,125 is 7125.

GCF of Denominators means GCF of 28,49,45 as per the given fractions.

GCF of 28,49,45 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 3,57,125

LCM of Fractions 3/28,57/49,125/45 is 7125

3 3, 57, 125
1, 19, 125

∴ So the LCM of the given numbers is 3 x 1 x 19 x 125 = 7125

Least Common Multiple of 3,57,125 with GCF Formula

Least Common Multiple of 3,57,125 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 3,57,125 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(3,57,125) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(3,57,125) x common factors =1 x 3 = 3

LCM(3,57,125) = ( 3 × 57 × 125 ) / 3

LCM(3,57,125) = 21375 / 3

LCM(3,57,125) = 7125


Lets's calculate GCF of 28,49,45

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7125/1

Therefore the LCM of Fractions 3/28,57/49,125/45 is 7125
