Lets's calculate LCM of 257,845
Given numbers has no common factors except 1. So, there LCM is their product i.e 217165
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/217165
Therefore, the GCF of Fractions 491/257,880/845 is 1/217165
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 257,845 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,845) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,845) x common factors =1 x 1 = 1
LCM(257,845) = ( 257 × 845 ) / 1
LCM(257,845) = 217165 / 1
LCM(257,845) = 217165
