Least Common Multiple of 13/98,21/21,171/501

Given numbers are 13/98,21/21,171/501

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 13,21,171

Least Common Multiple of Numerators i.e. LCM of 13,21,171 is 15561.

GCF of Denominators means GCF of 98,21,501 as per the given fractions.

GCF of 98,21,501 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 13,21,171

LCM of Fractions 13/98,21/21,171/501 is 15561

3 13, 21, 171
13, 7, 57

∴ So the LCM of the given numbers is 3 x 13 x 7 x 57 = 15561

Least Common Multiple of 13,21,171 with GCF Formula

Least Common Multiple of 13,21,171 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 13,21,171 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,21,171) = 1

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

GCF(13,21,171) x common factors =1 x 3 = 3

LCM(13,21,171) = ( 13 × 21 × 171 ) / 3

LCM(13,21,171) = 46683 / 3

LCM(13,21,171) = 15561


Lets's calculate GCF of 98,21,501

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 15561/1

Therefore the LCM of Fractions 13/98,21/21,171/501 is 15561
