Least Common Multiple of 64/20,244/12,645/289

Given numbers are 64/20,244/12,645/289

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 64,244,645

Least Common Multiple of Numerators i.e. LCM of 64,244,645 is 2518080.

GCF of Denominators means GCF of 20,12,289 as per the given fractions.

GCF of 20,12,289 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 64,244,645

LCM of Fractions 64/20,244/12,645/289 is 2518080

2 64, 244, 645
2 32, 122, 645
16, 61, 645

∴ So the LCM of the given numbers is 2 x 2 x 16 x 61 x 645 = 2518080

Least Common Multiple of 64,244,645 with GCF Formula

Least Common Multiple of 64,244,645 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 64,244,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(64,244,645) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(64,244,645) x common factors =1 x 4 = 4

LCM(64,244,645) = ( 64 × 244 × 645 ) / 4

LCM(64,244,645) = 10072320 / 4

LCM(64,244,645) = 2518080


Lets's calculate GCF of 20,12,289

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2518080/1

Therefore the LCM of Fractions 64/20,244/12,645/289 is 2518080
