Given numbers are 18/578,98/858,421/464

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 18,98,421

Least Common Multiple of Numerators i.e. LCM of 18,98,421 is 371322.

GCF of Denominators means GCF of 578,858,464 as per the given fractions.

GCF of 578,858,464 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 18,98,421

LCM of Fractions 18/578,98/858,421/464 is 185661

2 18, 98, 421
9, 49, 421

∴ So the LCM of the given numbers is 2 x 9 x 49 x 421 = 371322

Least Common Multiple of 18,98,421 with GCF Formula

Least Common Multiple of 18,98,421 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 18,98,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,98,421) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(18,98,421) x common factors =1 x 2 = 2

LCM(18,98,421) = ( 18 × 98 × 421 ) / 2

LCM(18,98,421) = 742644 / 2

LCM(18,98,421) = 371322


Lets's calculate GCF of 578,858,464

2 578, 858, 464
289, 429, 232

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 371322/2

Therefore the LCM of Fractions 18/578,98/858,421/464 is 185661
