Greatest Common Factor
We found the factors 721,7886 . The biggest common factor number is the GCF number.
So the greatest common factor 721,7886 is 1.
Lets's calculate LCM of 920,729
Given numbers has no common factors except 1. So, there LCM is their product i.e 670680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/670680
Therefore, the GCF of Fractions 721/920,7886/729 is 1/670680
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 920,729 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(920,729) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(920,729) x common factors =1 x 1 = 1
LCM(920,729) = ( 920 × 729 ) / 1
LCM(920,729) = 670680 / 1
LCM(920,729) = 670680
