So the greatest common factor 826,320 is 2.
Lets's calculate LCM of 797,972
Given numbers has no common factors except 1. So, there LCM is their product i.e 774684
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/774684
Therefore, the GCF of Fractions 826/797,320/972 is 2/774684
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 797,972 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(797,972) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(797,972) x common factors =1 x 1 = 1
LCM(797,972) = ( 797 × 972 ) / 1
LCM(797,972) = 774684 / 1
LCM(797,972) = 774684
