LCM of:

Least Common Multiple of 21/604,78/486,511/108

Given numbers are 21/604,78/486,511/108

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 21,78,511

Least Common Multiple of Numerators i.e. LCM of 21,78,511 is 39858.

GCF of Denominators means GCF of 604,486,108 as per the given fractions.

GCF of 604,486,108 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,78,511

LCM of Fractions 21/604,78/486,511/108 is 19929

3 21, 78, 511
7 7, 26, 511
1, 26, 73

∴ So the LCM of the given numbers is 3 x 7 x 1 x 26 x 73 = 39858

Least Common Multiple of 21,78,511 with GCF Formula

Least Common Multiple of 21,78,511 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 21,78,511 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,78,511) = 1

common factors(in case of two or more numbers have common factors) = 21

GCF(21,78,511) x common factors =1 x 21 = 21

LCM(21,78,511) = ( 21 × 78 × 511 ) / 21

LCM(21,78,511) = 837018 / 21

LCM(21,78,511) = 39858


Lets's calculate GCF of 604,486,108

2 604, 486, 108
302, 243, 54

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 39858/2

Therefore the LCM of Fractions 21/604,78/486,511/108 is 19929
