So the greatest common factor 798,730 is 2.
Lets's calculate LCM of 778,729
Given numbers has no common factors except 1. So, there LCM is their product i.e 567162
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/567162
Therefore, the GCF of Fractions 798/778,730/729 is 2/567162
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 778,729 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(778,729) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(778,729) x common factors =1 x 1 = 1
LCM(778,729) = ( 778 × 729 ) / 1
LCM(778,729) = 567162 / 1
LCM(778,729) = 567162
