Given numbers are 644/81,921/38,161/842

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 644,921,161

Least Common Multiple of Numerators i.e. LCM of 644,921,161 is 593124.

GCF of Denominators means GCF of 81,38,842 as per the given fractions.

GCF of 81,38,842 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 644,921,161

LCM of Fractions 644/81,921/38,161/842 is 593124

7 644, 921, 161
23 92, 921, 23
4, 921, 1

∴ So the LCM of the given numbers is 7 x 23 x 4 x 921 x 1 = 593124

Least Common Multiple of 644,921,161 with GCF Formula

Least Common Multiple of 644,921,161 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 644,921,161 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(644,921,161) = 1

common factors(in case of two or more numbers have common factors) = 161

GCF(644,921,161) x common factors =1 x 161 = 161

LCM(644,921,161) = ( 644 × 921 × 161 ) / 161

LCM(644,921,161) = 95492964 / 161

LCM(644,921,161) = 593124


Lets's calculate GCF of 81,38,842

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 593124/1

Therefore the LCM of Fractions 644/81,921/38,161/842 is 593124
