So the greatest common factor 447,978 is 3.
Lets's calculate LCM of 985,969
Given numbers has no common factors except 1. So, there LCM is their product i.e 954465
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/954465
Therefore, the GCF of Fractions 447/985,978/969 is 3/954465
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 985,969 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(985,969) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(985,969) x common factors =1 x 1 = 1
LCM(985,969) = ( 985 × 969 ) / 1
LCM(985,969) = 954465 / 1
LCM(985,969) = 954465
