Greatest Common Factor
We found the factors 709,791 . The biggest common factor number is the GCF number.
So the greatest common factor 709,791 is 1.
Lets's calculate LCM of 17,7517
Given numbers has no common factors except 1. So, there LCM is their product i.e 127789
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/127789
Therefore, the GCF of Fractions 709/17,791/7517 is 1/127789
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 17,7517 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,7517) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,7517) x common factors =1 x 1 = 1
LCM(17,7517) = ( 17 × 7517 ) / 1
LCM(17,7517) = 127789 / 1
LCM(17,7517) = 127789
