LCM of:

Least Common Multiple of 815/641,807/406

Given numbers are 815/641,807/406

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 815,807

Least Common Multiple of Numerators i.e. LCM of 815,807 is 657705.

GCF of Denominators means GCF of 641,406 as per the given fractions.

GCF of 641,406 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 815,807

LCM of Fractions 815/641,807/406 is 657705

Given numbers has no common factors except 1. So, there LCM is their product i.e 657705

Least Common Multiple of 815,807 with GCF Formula

Least Common Multiple of 815,807 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 815,807 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(815,807) = 1

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

GCF(815,807) x common factors =1 x 1 = 1

LCM(815,807) = ( 815 × 807 ) / 1

LCM(815,807) = 657705 / 1

LCM(815,807) = 657705


Lets's calculate GCF of 641,406

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 657705/1

Therefore the LCM of Fractions 815/641,807/406 is 657705
