Least Common Multiple of 421/81,784/3198

Given numbers are 421/81,784/3198

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 421,784

Least Common Multiple of Numerators i.e. LCM of 421,784 is 330064.

GCF of Denominators means GCF of 81,3198 as per the given fractions.

GCF of 81,3198 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 421,784

LCM of Fractions 421/81,784/3198 is 330064/3

Given numbers has no common factors except 1. So, there LCM is their product i.e 330064

Least Common Multiple of 421,784 with GCF Formula

Least Common Multiple of 421,784 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 421,784 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(421,784) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(421,784) x common factors =1 x 1 = 1

LCM(421,784) = ( 421 × 784 ) / 1

LCM(421,784) = 330064 / 1

LCM(421,784) = 330064


Lets's calculate GCF of 81,3198

3 81, 3198
27, 1066

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 330064/3

Therefore the LCM of Fractions 421/81,784/3198 is 330064/3
