Lets's calculate LCM of 390,811
Given numbers has no common factors except 1. So, there LCM is their product i.e 316290
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/316290
Therefore, the GCF of Fractions 408/390,743/811 is 1/316290
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 390,811 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,811) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(390,811) x common factors =1 x 1 = 1
LCM(390,811) = ( 390 × 811 ) / 1
LCM(390,811) = 316290 / 1
LCM(390,811) = 316290
