Lets's calculate LCM of 805,556
Given numbers has no common factors except 1. So, there LCM is their product i.e 447580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/447580
Therefore, the GCF of Fractions 445/805,678/556 is 1/447580
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 805,556 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(805,556) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(805,556) x common factors =1 x 1 = 1
LCM(805,556) = ( 805 × 556 ) / 1
LCM(805,556) = 447580 / 1
LCM(805,556) = 447580
