So the greatest common factor 985,391,378 is 1.

Lets's calculate LCM of 322,480,210

2 322, 480, 210
3 161, 240, 105
5 161, 80, 35
7 161, 16, 7
23, 16, 1

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 23 x 16 x 1 = 77280

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/77280

Least Common Multiple of 322,480,210 with GCF Formula

Least Common Multiple of 322,480,210 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 322,480,210 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(322,480,210) = 2

common factors(in case of two or more numbers have common factors) = 210

GCF(322,480,210) x common factors =2 x 210 = 420

LCM(322,480,210) = ( 322 × 480 × 210 ) / 420

LCM(322,480,210) = 32457600 / 420

LCM(322,480,210) = 77280
