GCF of Denominators means GCF of 123,690 as per the given fractions.

GCF of 123,690 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 645,6399

LCM of Fractions 645/123,6399/690 is 458595

3 645, 6399
215, 2133

∴ So the LCM of the given numbers is 3 x 215 x 2133 = 1375785

Least Common Multiple of 645,6399 with GCF Formula

Least Common Multiple of 645,6399 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 645,6399 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(645,6399) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(645,6399) x common factors =3 x 1 = 3

LCM(645,6399) = ( 645 × 6399 ) / 3

LCM(645,6399) = 4127355 / 3

LCM(645,6399) = 1375785


Lets's calculate GCF of 123,690

3 123, 690
41, 230

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1375785/3

Therefore the LCM of Fractions 645/123,6399/690 is 458595
