So the greatest common factor 779,897 is 1.
Lets's calculate LCM of 421,645
Given numbers has no common factors except 1. So, there LCM is their product i.e 271545
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/271545
Therefore, the GCF of Fractions 779/421,897/645 is 1/271545
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 421,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,645) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(421,645) x common factors =1 x 1 = 1
LCM(421,645) = ( 421 × 645 ) / 1
LCM(421,645) = 271545 / 1
LCM(421,645) = 271545
