Greatest Common Factor
We found the factors 510,391 . The biggest common factor number is the GCF number.
So the greatest common factor 510,391 is 17.
Lets's calculate LCM of 810,887
Given numbers has no common factors except 1. So, there LCM is their product i.e 718470
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/718470
Therefore, the GCF of Fractions 510/810,391/887 is 17/718470
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 810,887 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(810,887) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(810,887) x common factors =1 x 1 = 1
LCM(810,887) = ( 810 × 887 ) / 1
LCM(810,887) = 718470 / 1
LCM(810,887) = 718470
