Least Common Multiple of 20/74,509/21,655/973

Given numbers are 20/74,509/21,655/973

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 20,509,655

Least Common Multiple of Numerators i.e. LCM of 20,509,655 is 1333580.

GCF of Denominators means GCF of 74,21,973 as per the given fractions.

GCF of 74,21,973 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 20,509,655

LCM of Fractions 20/74,509/21,655/973 is 1333580

5 20, 509, 655
4, 509, 131

∴ So the LCM of the given numbers is 5 x 4 x 509 x 131 = 1333580

Least Common Multiple of 20,509,655 with GCF Formula

Least Common Multiple of 20,509,655 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 20,509,655 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,509,655) = 1

common factors(in case of two or more numbers have common factors) = 5

GCF(20,509,655) x common factors =1 x 5 = 5

LCM(20,509,655) = ( 20 × 509 × 655 ) / 5

LCM(20,509,655) = 6667900 / 5

LCM(20,509,655) = 1333580


Lets's calculate GCF of 74,21,973

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1333580/1

Therefore the LCM of Fractions 20/74,509/21,655/973 is 1333580
