Lets's calculate LCM of 205,443,427
Given numbers has no common factors except 1. So, there LCM is their product i.e 38778005
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38778005
Therefore, the GCF of Fractions 20/205,82/443,403/427 is 1/38778005
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 205,443,427 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(205,443,427) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(205,443,427) x common factors =1 x 1 = 1
LCM(205,443,427) = ( 205 × 443 × 427 ) / 1
LCM(205,443,427) = 38778005 / 1
LCM(205,443,427) = 38778005
