Least Common Multiple of 90/71,64/381,563/257

Given numbers are 90/71,64/381,563/257

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 90,64,563

Least Common Multiple of Numerators i.e. LCM of 90,64,563 is 1621440.

GCF of Denominators means GCF of 71,381,257 as per the given fractions.

GCF of 71,381,257 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 90,64,563

LCM of Fractions 90/71,64/381,563/257 is 1621440

2 90, 64, 563
45, 32, 563

∴ So the LCM of the given numbers is 2 x 45 x 32 x 563 = 1621440

Least Common Multiple of 90,64,563 with GCF Formula

Least Common Multiple of 90,64,563 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 90,64,563 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,64,563) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(90,64,563) x common factors =1 x 2 = 2

LCM(90,64,563) = ( 90 × 64 × 563 ) / 2

LCM(90,64,563) = 3242880 / 2

LCM(90,64,563) = 1621440


Lets's calculate GCF of 71,381,257

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1621440/1

Therefore the LCM of Fractions 90/71,64/381,563/257 is 1621440
