Lets's calculate LCM of 66,51,210

2 66, 51, 210
3 33, 51, 105
11, 17, 35

∴ So the LCM of the given numbers is 2 x 3 x 11 x 17 x 35 = 39270

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/39270

Therefore, the GCF of Fractions 28/66,29/51,12/210 is 1/39270

Least Common Multiple of 66,51,210 with GCF Formula

Least Common Multiple of 66,51,210 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 66,51,210 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,51,210) = 3

common factors(in case of two or more numbers have common factors) = 6

GCF(66,51,210) x common factors =3 x 6 = 18

LCM(66,51,210) = ( 66 × 51 × 210 ) / 18

LCM(66,51,210) = 706860 / 18

LCM(66,51,210) = 39270
