So the greatest common factor 85,800 is 5.


Lets's calculate LCM of 491,409

Given numbers has no common factors except 1. So, there LCM is their product i.e 200819

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/200819

Therefore, the GCF of Fractions 85/491,800/409 is 5/200819

Least Common Multiple of 491,409 with GCF Formula

Least Common Multiple of 491,409 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 491,409 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(491,409) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(491,409) x common factors =1 x 1 = 1

LCM(491,409) = ( 491 × 409 ) / 1

LCM(491,409) = 200819 / 1

LCM(491,409) = 200819
