So the greatest common factor 817,491 is 1.
Lets's calculate LCM of 998,573
Given numbers has no common factors except 1. So, there LCM is their product i.e 571854
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/571854
Therefore, the GCF of Fractions 817/998,491/573 is 1/571854
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 998,573 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(998,573) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(998,573) x common factors =1 x 1 = 1
LCM(998,573) = ( 998 × 573 ) / 1
LCM(998,573) = 571854 / 1
LCM(998,573) = 571854
