Least Common Multiple of 78/85,139/38,880/168

Given numbers are 78/85,139/38,880/168

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 78,139,880

Least Common Multiple of Numerators i.e. LCM of 78,139,880 is 4770480.

GCF of Denominators means GCF of 85,38,168 as per the given fractions.

GCF of 85,38,168 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,139,880

LCM of Fractions 78/85,139/38,880/168 is 4770480

2 78, 139, 880
39, 139, 440

∴ So the LCM of the given numbers is 2 x 39 x 139 x 440 = 4770480

Least Common Multiple of 78,139,880 with GCF Formula

Least Common Multiple of 78,139,880 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 78,139,880 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,139,880) = 1

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

GCF(78,139,880) x common factors =1 x 2 = 2

LCM(78,139,880) = ( 78 × 139 × 880 ) / 2

LCM(78,139,880) = 9540960 / 2

LCM(78,139,880) = 4770480


Lets's calculate GCF of 85,38,168

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4770480/1

Therefore the LCM of Fractions 78/85,139/38,880/168 is 4770480
