LCM of:

Least Common Multiple of 84/75,39/680,798/839

Given numbers are 84/75,39/680,798/839

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 84,39,798

Least Common Multiple of Numerators i.e. LCM of 84,39,798 is 20748.

GCF of Denominators means GCF of 75,680,839 as per the given fractions.

GCF of 75,680,839 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 84,39,798

LCM of Fractions 84/75,39/680,798/839 is 20748

2 84, 39, 798
3 42, 39, 399
7 14, 13, 133
2, 13, 19

∴ So the LCM of the given numbers is 2 x 3 x 7 x 2 x 13 x 19 = 20748

Least Common Multiple of 84,39,798 with GCF Formula

Least Common Multiple of 84,39,798 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 84,39,798 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,39,798) = 3

common factors(in case of two or more numbers have common factors) = 42

GCF(84,39,798) x common factors =3 x 42 = 126

LCM(84,39,798) = ( 84 × 39 × 798 ) / 126

LCM(84,39,798) = 2614248 / 126

LCM(84,39,798) = 20748


Lets's calculate GCF of 75,680,839

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 20748/1

Therefore the LCM of Fractions 84/75,39/680,798/839 is 20748
