Least Common Multiple of 642/78,111/51,981/609

Given numbers are 642/78,111/51,981/609

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 642,111,981

Least Common Multiple of Numerators i.e. LCM of 642,111,981 is 7767558.

GCF of Denominators means GCF of 78,51,609 as per the given fractions.

GCF of 78,51,609 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 642,111,981

LCM of Fractions 642/78,111/51,981/609 is 2589186

3 642, 111, 981
214, 37, 327

∴ So the LCM of the given numbers is 3 x 214 x 37 x 327 = 7767558

Least Common Multiple of 642,111,981 with GCF Formula

Least Common Multiple of 642,111,981 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 642,111,981 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(642,111,981) = 3

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

GCF(642,111,981) x common factors =3 x 3 = 9

LCM(642,111,981) = ( 642 × 111 × 981 ) / 9

LCM(642,111,981) = 69908022 / 9

LCM(642,111,981) = 7767558


Lets's calculate GCF of 78,51,609

3 78, 51, 609
26, 17, 203

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7767558/3

Therefore the LCM of Fractions 642/78,111/51,981/609 is 2589186
