So the greatest common factor 30,12,220 is 2.

Lets's calculate LCM of 17,54,33

3 17, 54, 33
17, 18, 11

∴ So the LCM of the given numbers is 3 x 17 x 18 x 11 = 10098

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/10098

Therefore, the GCF of Fractions 30/17,12/54,220/33 is 2/10098

Least Common Multiple of 17,54,33 with GCF Formula

Least Common Multiple of 17,54,33 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 17,54,33 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(17,54,33) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(17,54,33) x common factors =1 x 3 = 3

LCM(17,54,33) = ( 17 × 54 × 33 ) / 3

LCM(17,54,33) = 30294 / 3

LCM(17,54,33) = 10098
