Least Common Multiple of 231/85,704/20,351/87

Given numbers are 231/85,704/20,351/87

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 231,704,351

Least Common Multiple of Numerators i.e. LCM of 231,704,351 is 1729728.

GCF of Denominators means GCF of 85,20,87 as per the given fractions.

GCF of 85,20,87 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 231,704,351

LCM of Fractions 231/85,704/20,351/87 is 1729728

3 231, 704, 351
11 77, 704, 117
7, 64, 117

∴ So the LCM of the given numbers is 3 x 11 x 7 x 64 x 117 = 1729728

Least Common Multiple of 231,704,351 with GCF Formula

Least Common Multiple of 231,704,351 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 231,704,351 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(231,704,351) = 1

common factors(in case of two or more numbers have common factors) = 33

GCF(231,704,351) x common factors =1 x 33 = 33

LCM(231,704,351) = ( 231 × 704 × 351 ) / 33

LCM(231,704,351) = 57081024 / 33

LCM(231,704,351) = 1729728


Lets's calculate GCF of 85,20,87

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1729728/1

Therefore the LCM of Fractions 231/85,704/20,351/87 is 1729728
