Lets's calculate LCM of 685,559
Given numbers has no common factors except 1. So, there LCM is their product i.e 382915
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/382915
Therefore, the GCF of Fractions 210/685,1844/559 is 2/382915
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 685,559 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(685,559) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(685,559) x common factors =1 x 1 = 1
LCM(685,559) = ( 685 × 559 ) / 1
LCM(685,559) = 382915 / 1
LCM(685,559) = 382915
