Greatest Common Factor
We found the factors 515,811 . The biggest common factor number is the GCF number.
So the greatest common factor 515,811 is 1.
Lets's calculate LCM of 780,929
Given numbers has no common factors except 1. So, there LCM is their product i.e 724620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/724620
Therefore, the GCF of Fractions 515/780,811/929 is 1/724620
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 780,929 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,929) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(780,929) x common factors =1 x 1 = 1
LCM(780,929) = ( 780 × 929 ) / 1
LCM(780,929) = 724620 / 1
LCM(780,929) = 724620
