Least Common Multiple of 75/38,30/70,647/45

Given numbers are 75/38,30/70,647/45

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 75,30,647

Least Common Multiple of Numerators i.e. LCM of 75,30,647 is 97050.

GCF of Denominators means GCF of 38,70,45 as per the given fractions.

GCF of 38,70,45 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 75,30,647

LCM of Fractions 75/38,30/70,647/45 is 97050

3 75, 30, 647
5 25, 10, 647
5, 2, 647

∴ So the LCM of the given numbers is 3 x 5 x 5 x 2 x 647 = 97050

Least Common Multiple of 75,30,647 with GCF Formula

Least Common Multiple of 75,30,647 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 75,30,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(75,30,647) = 1

common factors(in case of two or more numbers have common factors) = 15

GCF(75,30,647) x common factors =1 x 15 = 15

LCM(75,30,647) = ( 75 × 30 × 647 ) / 15

LCM(75,30,647) = 1455750 / 15

LCM(75,30,647) = 97050


Lets's calculate GCF of 38,70,45

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 97050/1

Therefore the LCM of Fractions 75/38,30/70,647/45 is 97050
