Least Common Multiple of 75/30,57/50,15/91,38/640

Given numbers are 75/30,57/50,15/91,38/640

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 75,57,15,38

Least Common Multiple of Numerators i.e. LCM of 75,57,15,38 is 2850.

GCF of Denominators means GCF of 30,50,91,640 as per the given fractions.

GCF of 30,50,91,640 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 75,57,15,38

LCM of Fractions 75/30,57/50,15/91,38/640 is 2850

3 75, 57, 15, 38
5 25, 19, 5, 38
19 1, 19, 5, 38
1, 1, 5, 2

∴ So the LCM of the given numbers is 3 x 5 x 19 x 1 x 1 x 5 x 2 = 2850

Least Common Multiple of 75,57,15,38 with GCF Formula

Least Common Multiple of 75,57,15,38 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 75,57,15,38 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(75,57,15,38) = 1

common factors(in case of two or more numbers have common factors) = 855

GCF(75,57,15,38) x common factors =1 x 855 = 855

LCM(75,57,15,38) = ( 75 × 57 × 15 × 38 ) / 855

LCM(75,57,15,38) = 2436750 / 855

LCM(75,57,15,38) = 2850


Lets's calculate GCF of 30,50,91,640

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2850/1

Therefore the LCM of Fractions 75/30,57/50,15/91,38/640 is 2850
