Lets's calculate LCM of 211,981,911
Given numbers has no common factors except 1. So, there LCM is their product i.e 188568801
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/188568801
Therefore, the GCF of Fractions 82/211,457/981,821/911 is 1/188568801
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 211,981,911 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(211,981,911) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(211,981,911) x common factors =1 x 1 = 1
LCM(211,981,911) = ( 211 × 981 × 911 ) / 1
LCM(211,981,911) = 188568801 / 1
LCM(211,981,911) = 188568801
