Least Common Multiple of 561/38,238/1989

Given numbers are 561/38,238/1989

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 561,238

Least Common Multiple of Numerators i.e. LCM of 561,238 is 7854.

GCF of Denominators means GCF of 38,1989 as per the given fractions.

GCF of 38,1989 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 561,238

LCM of Fractions 561/38,238/1989 is 7854

17 561, 238
33, 14

∴ So the LCM of the given numbers is 17 x 33 x 14 = 7854

Least Common Multiple of 561,238 with GCF Formula

Least Common Multiple of 561,238 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 561,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(561,238) = 17

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

GCF(561,238) x common factors =17 x 1 = 17

LCM(561,238) = ( 561 × 238 ) / 17

LCM(561,238) = 133518 / 17

LCM(561,238) = 7854


Lets's calculate GCF of 38,1989

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7854/1

Therefore the LCM of Fractions 561/38,238/1989 is 7854
