Lets's calculate LCM of 25,9817
Given numbers has no common factors except 1. So, there LCM is their product i.e 245425
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/245425
Therefore, the GCF of Fractions 638/25,513/9817 is 1/245425
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 25,9817 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,9817) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(25,9817) x common factors =1 x 1 = 1
LCM(25,9817) = ( 25 × 9817 ) / 1
LCM(25,9817) = 245425 / 1
LCM(25,9817) = 245425
