So the greatest common factor 806,390 is 26.
Lets's calculate LCM of 557,816
Given numbers has no common factors except 1. So, there LCM is their product i.e 454512
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 26/454512
Therefore, the GCF of Fractions 806/557,390/816 is 26/454512
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 557,816 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(557,816) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(557,816) x common factors =1 x 1 = 1
LCM(557,816) = ( 557 × 816 ) / 1
LCM(557,816) = 454512 / 1
LCM(557,816) = 454512
