Lets's calculate LCM of 809,2249
Given numbers has no common factors except 1. So, there LCM is their product i.e 1819441
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/1819441
Therefore, the GCF of Fractions 486/809,1920/2249 is 6/1819441
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 809,2249 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(809,2249) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(809,2249) x common factors =1 x 1 = 1
LCM(809,2249) = ( 809 × 2249 ) / 1
LCM(809,2249) = 1819441 / 1
LCM(809,2249) = 1819441
