Lets's calculate LCM of 30,34,84

2 30, 34, 84
3 15, 17, 42
5, 17, 14

∴ So the LCM of the given numbers is 2 x 3 x 5 x 17 x 14 = 7140

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/7140

Therefore, the GCF of Fractions 813/30,987/34,906/84 is 3/7140

Least Common Multiple of 30,34,84 with GCF Formula

Least Common Multiple of 30,34,84 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 30,34,84 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(30,34,84) = 2

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

GCF(30,34,84) x common factors =2 x 6 = 12

LCM(30,34,84) = ( 30 × 34 × 84 ) / 12

LCM(30,34,84) = 85680 / 12

LCM(30,34,84) = 7140
