So the greatest common factor 692,512 is 4.
Lets's calculate LCM of 821,856
Given numbers has no common factors except 1. So, there LCM is their product i.e 702776
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/702776
Therefore, the GCF of Fractions 692/821,512/856 is 4/702776
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 821,856 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,856) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,856) x common factors =1 x 1 = 1
LCM(821,856) = ( 821 × 856 ) / 1
LCM(821,856) = 702776 / 1
LCM(821,856) = 702776
