So the greatest common factor 213,430 is 1.
Lets's calculate LCM of 687,329
Given numbers has no common factors except 1. So, there LCM is their product i.e 226023
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/226023
Therefore, the GCF of Fractions 213/687,430/329 is 1/226023
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 687,329 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,329) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(687,329) x common factors =1 x 1 = 1
LCM(687,329) = ( 687 × 329 ) / 1
LCM(687,329) = 226023 / 1
LCM(687,329) = 226023
