Lets's calculate LCM of 809,686
Given numbers has no common factors except 1. So, there LCM is their product i.e 554974
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/554974
Therefore, the GCF of Fractions 502/809,312/686 is 2/554974
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 809,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(809,686) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(809,686) x common factors =1 x 1 = 1
LCM(809,686) = ( 809 × 686 ) / 1
LCM(809,686) = 554974 / 1
LCM(809,686) = 554974
