Greatest Common Factor
We found the factors 678,608,811 . The biggest common factor number is the GCF number.
So the greatest common factor 678,608,811 is 1.
Lets's calculate LCM of 721,307,359
Given numbers has no common factors except 1. So, there LCM is their product i.e 79463573
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/79463573
Therefore, the GCF of Fractions 678/721,608/307,811/359 is 1/79463573
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 721,307,359 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(721,307,359) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(721,307,359) x common factors =1 x 1 = 1
LCM(721,307,359) = ( 721 × 307 × 359 ) / 1
LCM(721,307,359) = 79463573 / 1
LCM(721,307,359) = 79463573
Here are some samples of GCF of Fractions calculations.
