LCM of:

Least Common Multiple of 72/18,287/40,241/630

Given numbers are 72/18,287/40,241/630

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 72,287,241

Least Common Multiple of Numerators i.e. LCM of 72,287,241 is 4980024.

GCF of Denominators means GCF of 18,40,630 as per the given fractions.

GCF of 18,40,630 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 72,287,241

LCM of Fractions 72/18,287/40,241/630 is 2490012

Given numbers has no common factors except 1. So, there LCM is their product i.e 4980024

Least Common Multiple of 72,287,241 with GCF Formula

Least Common Multiple of 72,287,241 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 72,287,241 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,287,241) = 1

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

GCF(72,287,241) x common factors =1 x 1 = 1

LCM(72,287,241) = ( 72 × 287 × 241 ) / 1

LCM(72,287,241) = 4980024 / 1

LCM(72,287,241) = 4980024


Lets's calculate GCF of 18,40,630

2 18, 40, 630
9, 20, 315

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4980024/2

Therefore the LCM of Fractions 72/18,287/40,241/630 is 2490012
