Lets's calculate LCM of 81,27,391

3 81, 27, 391
3 27, 9, 391
3 3, 9, 391
1, 3, 391

∴ So the LCM of the given numbers is 3 x 3 x 3 x 1 x 3 x 391 = 31671

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/31671

Therefore, the GCF of Fractions 17/81,93/27,14/391 is 1/31671

Least Common Multiple of 81,27,391 with GCF Formula

Least Common Multiple of 81,27,391 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 81,27,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,27,391) = 1

common factors(in case of two or more numbers have common factors) = 27

GCF(81,27,391) x common factors =1 x 27 = 27

LCM(81,27,391) = ( 81 × 27 × 391 ) / 27

LCM(81,27,391) = 855117 / 27

LCM(81,27,391) = 31671
