Given numbers are 21/621,48/729,798/612

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 21,48,798

Least Common Multiple of Numerators i.e. LCM of 21,48,798 is 6384.

GCF of Denominators means GCF of 621,729,612 as per the given fractions.

GCF of 621,729,612 is 9 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,48,798

LCM of Fractions 21/621,48/729,798/612 is 6384/9

2 21, 48, 798
3 21, 24, 399
7 7, 8, 133
1, 8, 19

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 8 x 19 = 6384

Least Common Multiple of 21,48,798 with GCF Formula

Least Common Multiple of 21,48,798 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 21,48,798 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,48,798) = 3

common factors(in case of two or more numbers have common factors) = 42

GCF(21,48,798) x common factors =3 x 42 = 126

LCM(21,48,798) = ( 21 × 48 × 798 ) / 126

LCM(21,48,798) = 804384 / 126

LCM(21,48,798) = 6384


Lets's calculate GCF of 621,729,612

3 621, 729, 612
3 207, 243, 204
69, 81, 68

∴ So the GCF of the given numbers is 3 x 3 = 9

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6384/9

Therefore the LCM of Fractions 21/621,48/729,798/612 is 6384/9
