So the greatest common factor 197,208 is 1.
Lets's calculate LCM of 239,438
Given numbers has no common factors except 1. So, there LCM is their product i.e 104682
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/104682
Therefore, the GCF of Fractions 197/239,208/438 is 1/104682
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 239,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(239,438) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(239,438) x common factors =1 x 1 = 1
LCM(239,438) = ( 239 × 438 ) / 1
LCM(239,438) = 104682 / 1
LCM(239,438) = 104682
