Lets's calculate LCM of 687,811
Given numbers has no common factors except 1. So, there LCM is their product i.e 557157
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/557157
Therefore, the GCF of Fractions 568/687,623/811 is 1/557157
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 687,811 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,811) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(687,811) x common factors =1 x 1 = 1
LCM(687,811) = ( 687 × 811 ) / 1
LCM(687,811) = 557157 / 1
LCM(687,811) = 557157
