Lets's calculate LCM of 545,771
Given numbers has no common factors except 1. So, there LCM is their product i.e 420195
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/420195
Therefore, the GCF of Fractions 808/545,405/771 is 1/420195
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 545,771 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(545,771) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(545,771) x common factors =1 x 1 = 1
LCM(545,771) = ( 545 × 771 ) / 1
LCM(545,771) = 420195 / 1
LCM(545,771) = 420195
