Lets's calculate LCM of 445,289
Given numbers has no common factors except 1. So, there LCM is their product i.e 128605
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/128605
Therefore, the GCF of Fractions 814/445,480/289 is 2/128605
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 445,289 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(445,289) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(445,289) x common factors =1 x 1 = 1
LCM(445,289) = ( 445 × 289 ) / 1
LCM(445,289) = 128605 / 1
LCM(445,289) = 128605
