Least Common Multiple of 23/16,287/43,721/561

Given numbers are 23/16,287/43,721/561

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 23,287,721

Least Common Multiple of Numerators i.e. LCM of 23,287,721 is 679903.

GCF of Denominators means GCF of 16,43,561 as per the given fractions.

GCF of 16,43,561 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 23,287,721

LCM of Fractions 23/16,287/43,721/561 is 679903

7 23, 287, 721
23, 41, 103

∴ So the LCM of the given numbers is 7 x 23 x 41 x 103 = 679903

Least Common Multiple of 23,287,721 with GCF Formula

Least Common Multiple of 23,287,721 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 23,287,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(23,287,721) = 1

common factors(in case of two or more numbers have common factors) = 7

GCF(23,287,721) x common factors =1 x 7 = 7

LCM(23,287,721) = ( 23 × 287 × 721 ) / 7

LCM(23,287,721) = 4759321 / 7

LCM(23,287,721) = 679903


Lets's calculate GCF of 16,43,561

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 679903/1

Therefore the LCM of Fractions 23/16,287/43,721/561 is 679903
