Least Common Multiple of 312/72,400/86,491/728

Given numbers are 312/72,400/86,491/728

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 312,400,491

Least Common Multiple of Numerators i.e. LCM of 312,400,491 is 7659600.

GCF of Denominators means GCF of 72,86,728 as per the given fractions.

GCF of 72,86,728 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 312,400,491

LCM of Fractions 312/72,400/86,491/728 is 3829800

2 312, 400, 491
2 156, 200, 491
2 78, 100, 491
39, 50, 491

∴ So the LCM of the given numbers is 2 x 2 x 2 x 39 x 50 x 491 = 7659600

Least Common Multiple of 312,400,491 with GCF Formula

Least Common Multiple of 312,400,491 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 312,400,491 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(312,400,491) = 1

common factors(in case of two or more numbers have common factors) = 8

GCF(312,400,491) x common factors =1 x 8 = 8

LCM(312,400,491) = ( 312 × 400 × 491 ) / 8

LCM(312,400,491) = 61276800 / 8

LCM(312,400,491) = 7659600


Lets's calculate GCF of 72,86,728

2 72, 86, 728
36, 43, 364

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7659600/2

Therefore the LCM of Fractions 312/72,400/86,491/728 is 3829800
