Least Common Multiple of 815/28,840/35,605/420

Given numbers are 815/28,840/35,605/420

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 815,840,605

Least Common Multiple of Numerators i.e. LCM of 815,840,605 is 16567320.

GCF of Denominators means GCF of 28,35,420 as per the given fractions.

GCF of 28,35,420 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 815,840,605

LCM of Fractions 815/28,840/35,605/420 is 2366760

5 815, 840, 605
163, 168, 121

∴ So the LCM of the given numbers is 5 x 163 x 168 x 121 = 16567320

Least Common Multiple of 815,840,605 with GCF Formula

Least Common Multiple of 815,840,605 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 815,840,605 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(815,840,605) = 5

common factors(in case of two or more numbers have common factors) = 5

GCF(815,840,605) x common factors =5 x 5 = 25

LCM(815,840,605) = ( 815 × 840 × 605 ) / 25

LCM(815,840,605) = 414183000 / 25

LCM(815,840,605) = 16567320


Lets's calculate GCF of 28,35,420

7 28, 35, 420
4, 5, 60

∴ So the GCF of the given numbers is 7 = 7

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 16567320/7

Therefore the LCM of Fractions 815/28,840/35,605/420 is 2366760
