Lets's calculate LCM of 27,99,12,394

2 27, 99, 12, 394
3 27, 99, 6, 197
3 9, 33, 2, 197
3, 11, 2, 197

∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 11 x 2 x 197 = 234036

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/234036

Therefore, the GCF of Fractions 71/27,57/99,86/12,13/394 is 1/234036

Least Common Multiple of 27,99,12,394 with GCF Formula

Least Common Multiple of 27,99,12,394 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 27,99,12,394 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(27,99,12,394) = 1

common factors(in case of two or more numbers have common factors) = 54

GCF(27,99,12,394) x common factors =1 x 54 = 54

LCM(27,99,12,394) = ( 27 × 99 × 12 × 394 ) / 54

LCM(27,99,12,394) = 12637944 / 54

LCM(27,99,12,394) = 234036
