Lets's calculate LCM of 409,686
Given numbers has no common factors except 1. So, there LCM is their product i.e 280574
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/280574
Therefore, the GCF of Fractions 497/409,208/686 is 1/280574
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 409,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(409,686) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(409,686) x common factors =1 x 1 = 1
LCM(409,686) = ( 409 × 686 ) / 1
LCM(409,686) = 280574 / 1
LCM(409,686) = 280574
