So the greatest common factor 498,902 is 2.
Lets's calculate LCM of 397,974
Given numbers has no common factors except 1. So, there LCM is their product i.e 386678
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/386678
Therefore, the GCF of Fractions 498/397,902/974 is 2/386678
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 397,974 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(397,974) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(397,974) x common factors =1 x 1 = 1
LCM(397,974) = ( 397 × 974 ) / 1
LCM(397,974) = 386678 / 1
LCM(397,974) = 386678
