LCM of 431/33, 647/405

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 431/33,647/405

Given numbers are 431/33,647/405

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 431,647

Least Common Multiple of Numerators i.e. LCM of 431,647 is 278857.

GCF of Denominators means GCF of 33,405 as per the given fractions.

GCF of 33,405 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 431,647

LCM of Fractions 431/33,647/405 is 278857/3

Given numbers has no common factors except 1. So, there LCM is their product i.e 278857

Least Common Multiple of 431,647 with GCF Formula

Least Common Multiple of 431,647 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 431,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(431,647) = 1

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

GCF(431,647) x common factors =1 x 1 = 1

LCM(431,647) = ( 431 × 647 ) / 1

LCM(431,647) = 278857 / 1

LCM(431,647) = 278857


Lets's calculate GCF of 33,405

3 33, 405
11, 135

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 278857/3

Therefore the LCM of Fractions 431/33,647/405 is 278857/3
