So the greatest common factor 558,455 is 1.
Lets's calculate LCM of 817,185
Given numbers has no common factors except 1. So, there LCM is their product i.e 151145
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/151145
Therefore, the GCF of Fractions 558/817,455/185 is 1/151145
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 817,185 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(817,185) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(817,185) x common factors =1 x 1 = 1
LCM(817,185) = ( 817 × 185 ) / 1
LCM(817,185) = 151145 / 1
LCM(817,185) = 151145
