Lets's calculate LCM of 81,33,231

3 81, 33, 231
11 27, 11, 77
27, 1, 7

∴ So the LCM of the given numbers is 3 x 11 x 27 x 1 x 7 = 6237

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6237

Therefore, the GCF of Fractions 100/81,196/33,669/231 is 1/6237

Least Common Multiple of 81,33,231 with GCF Formula

Least Common Multiple of 81,33,231 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 81,33,231 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,33,231) = 3

common factors(in case of two or more numbers have common factors) = 33

GCF(81,33,231) x common factors =3 x 33 = 99

LCM(81,33,231) = ( 81 × 33 × 231 ) / 99

LCM(81,33,231) = 617463 / 99

LCM(81,33,231) = 6237
