So the greatest common factor 256,216 is 8.
Lets's calculate LCM of 685,806
Given numbers has no common factors except 1. So, there LCM is their product i.e 552110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/552110
Therefore, the GCF of Fractions 256/685,216/806 is 8/552110
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 685,806 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(685,806) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(685,806) x common factors =1 x 1 = 1
LCM(685,806) = ( 685 × 806 ) / 1
LCM(685,806) = 552110 / 1
LCM(685,806) = 552110
