Least Common Multiple of 11/81,213/69,521/645

Given numbers are 11/81,213/69,521/645

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 11,213,521

Least Common Multiple of Numerators i.e. LCM of 11,213,521 is 1220703.

GCF of Denominators means GCF of 81,69,645 as per the given fractions.

GCF of 81,69,645 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 11,213,521

LCM of Fractions 11/81,213/69,521/645 is 406901

Given numbers has no common factors except 1. So, there LCM is their product i.e 1220703

Least Common Multiple of 11,213,521 with GCF Formula

Least Common Multiple of 11,213,521 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 11,213,521 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(11,213,521) = 1

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

GCF(11,213,521) x common factors =1 x 1 = 1

LCM(11,213,521) = ( 11 × 213 × 521 ) / 1

LCM(11,213,521) = 1220703 / 1

LCM(11,213,521) = 1220703


Lets's calculate GCF of 81,69,645

3 81, 69, 645
27, 23, 215

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1220703/3

Therefore the LCM of Fractions 11/81,213/69,521/645 is 406901
