Lets's calculate LCM of 30,81,63,819

3 30, 81, 63, 819
3 10, 27, 21, 273
7 10, 9, 7, 91
10, 9, 1, 13

∴ So the LCM of the given numbers is 3 x 3 x 7 x 10 x 9 x 1 x 13 = 73710

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/73710

Least Common Multiple of 30,81,63,819 with GCF Formula

Least Common Multiple of 30,81,63,819 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 30,81,63,819 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(30,81,63,819) = 3

common factors(in case of two or more numbers have common factors) = 567

GCF(30,81,63,819) x common factors =3 x 567 = 1701

LCM(30,81,63,819) = ( 30 × 81 × 63 × 819 ) / 1701

LCM(30,81,63,819) = 125380710 / 1701

LCM(30,81,63,819) = 73710
