Given numbers are 393/450,879/613,640/742

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 393,879,640

Least Common Multiple of Numerators i.e. LCM of 393,879,640 is 73695360.

GCF of Denominators means GCF of 450,613,742 as per the given fractions.

GCF of 450,613,742 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 393,879,640

LCM of Fractions 393/450,879/613,640/742 is 73695360

3 393, 879, 640
131, 293, 640

∴ So the LCM of the given numbers is 3 x 131 x 293 x 640 = 73695360

Least Common Multiple of 393,879,640 with GCF Formula

Least Common Multiple of 393,879,640 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 393,879,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(393,879,640) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(393,879,640) x common factors =1 x 3 = 3

LCM(393,879,640) = ( 393 × 879 × 640 ) / 3

LCM(393,879,640) = 221086080 / 3

LCM(393,879,640) = 73695360


Lets's calculate GCF of 450,613,742

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 73695360/1

Therefore the LCM of Fractions 393/450,879/613,640/742 is 73695360
