So the greatest common factor 30,10,998 is 2.


Lets's calculate LCM of 69,30,510

2 69, 30, 510
3 69, 15, 255
5 23, 5, 85
23, 1, 17

∴ So the LCM of the given numbers is 2 x 3 x 5 x 23 x 1 x 17 = 11730

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/11730

Therefore, the GCF of Fractions 30/69,10/30,998/510 is 2/11730

Least Common Multiple of 69,30,510 with GCF Formula

Least Common Multiple of 69,30,510 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 69,30,510 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(69,30,510) = 3

common factors(in case of two or more numbers have common factors) = 30

GCF(69,30,510) x common factors =3 x 30 = 90

LCM(69,30,510) = ( 69 × 30 × 510 ) / 90

LCM(69,30,510) = 1055700 / 90

LCM(69,30,510) = 11730
