Greatest Common Factor
We found the factors 729,8171 . The biggest common factor number is the GCF number.
So the greatest common factor 729,8171 is 1.
Lets's calculate LCM of 728,771
Given numbers has no common factors except 1. So, there LCM is their product i.e 561288
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/561288
Therefore, the GCF of Fractions 729/728,8171/771 is 1/561288
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 728,771 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(728,771) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(728,771) x common factors =1 x 1 = 1
LCM(728,771) = ( 728 × 771 ) / 1
LCM(728,771) = 561288 / 1
LCM(728,771) = 561288
