Least Common Multiple of 90/19,33/49,909/161

Given numbers are 90/19,33/49,909/161

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 90,33,909

Least Common Multiple of Numerators i.e. LCM of 90,33,909 is 99990.

GCF of Denominators means GCF of 19,49,161 as per the given fractions.

GCF of 19,49,161 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 90,33,909

LCM of Fractions 90/19,33/49,909/161 is 99990

3 90, 33, 909
3 30, 11, 303
10, 11, 101

∴ So the LCM of the given numbers is 3 x 3 x 10 x 11 x 101 = 99990

Least Common Multiple of 90,33,909 with GCF Formula

Least Common Multiple of 90,33,909 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 90,33,909 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,33,909) = 3

common factors(in case of two or more numbers have common factors) = 9

GCF(90,33,909) x common factors =3 x 9 = 27

LCM(90,33,909) = ( 90 × 33 × 909 ) / 27

LCM(90,33,909) = 2699730 / 27

LCM(90,33,909) = 99990


Lets's calculate GCF of 19,49,161

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 99990/1

Therefore the LCM of Fractions 90/19,33/49,909/161 is 99990
