Lets's calculate LCM of 406,309
Given numbers has no common factors except 1. So, there LCM is their product i.e 125454
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/125454
Therefore, the GCF of Fractions 488/406,658/309 is 2/125454
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 406,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(406,309) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(406,309) x common factors =1 x 1 = 1
LCM(406,309) = ( 406 × 309 ) / 1
LCM(406,309) = 125454 / 1
LCM(406,309) = 125454
