Least Common Multiple of 45/24,54/42,19/84,56/909

Given numbers are 45/24,54/42,19/84,56/909

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 45,54,19,56

Least Common Multiple of Numerators i.e. LCM of 45,54,19,56 is 143640.

GCF of Denominators means GCF of 24,42,84,909 as per the given fractions.

GCF of 24,42,84,909 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 45,54,19,56

LCM of Fractions 45/24,54/42,19/84,56/909 is 47880

2 45, 54, 19, 56
3 45, 27, 19, 28
3 15, 9, 19, 28
5, 3, 19, 28

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 3 x 19 x 28 = 143640

Least Common Multiple of 45,54,19,56 with GCF Formula

Least Common Multiple of 45,54,19,56 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 45,54,19,56 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,54,19,56) = 1

common factors(in case of two or more numbers have common factors) = 18

GCF(45,54,19,56) x common factors =1 x 18 = 18

LCM(45,54,19,56) = ( 45 × 54 × 19 × 56 ) / 18

LCM(45,54,19,56) = 2585520 / 18

LCM(45,54,19,56) = 143640


Lets's calculate GCF of 24,42,84,909

3 24, 42, 84, 909
8, 14, 28, 303

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 143640/3

Therefore the LCM of Fractions 45/24,54/42,19/84,56/909 is 47880
