Lets's calculate LCM of 81,27,97

3 81, 27, 97
3 27, 9, 97
3 3, 9, 97
1, 3, 97

∴ So the LCM of the given numbers is 3 x 3 x 3 x 1 x 3 x 97 = 7857

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7857

Therefore, the GCF of Fractions 120/81,909/27,809/97 is 1/7857

Least Common Multiple of 81,27,97 with GCF Formula

Least Common Multiple of 81,27,97 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 81,27,97 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,27,97) = 1

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

GCF(81,27,97) x common factors =1 x 27 = 27

LCM(81,27,97) = ( 81 × 27 × 97 ) / 27

LCM(81,27,97) = 212139 / 27

LCM(81,27,97) = 7857
