Given numbers are 405/691,873/478,457/239

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 405,873,457

Least Common Multiple of Numerators i.e. LCM of 405,873,457 is 17953245.

GCF of Denominators means GCF of 691,478,239 as per the given fractions.

GCF of 691,478,239 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 405,873,457

LCM of Fractions 405/691,873/478,457/239 is 17953245

3 405, 873, 457
3 135, 291, 457
45, 97, 457

∴ So the LCM of the given numbers is 3 x 3 x 45 x 97 x 457 = 17953245

Least Common Multiple of 405,873,457 with GCF Formula

Least Common Multiple of 405,873,457 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 405,873,457 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(405,873,457) = 1

common factors(in case of two or more numbers have common factors) = 9

GCF(405,873,457) x common factors =1 x 9 = 9

LCM(405,873,457) = ( 405 × 873 × 457 ) / 9

LCM(405,873,457) = 161579205 / 9

LCM(405,873,457) = 17953245


Lets's calculate GCF of 691,478,239

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 17953245/1

Therefore the LCM of Fractions 405/691,873/478,457/239 is 17953245
