Lets's calculate GCF of 819,857
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 819
:1,3,7,9,13,21,39,63,91,117,273,819
Now, list down the factors of 857
:1,857
Greatest Common Factor
We found the factors 819,857 . The biggest common factor number is the GCF number.
So the greatest common factor 819,857 is 1.
Lets's calculate LCM of 710,771
Given numbers has no common factors except 1. So, there LCM is their product i.e 547410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/547410
Therefore, the GCF of Fractions 819/710,857/771 is 1/547410
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 710,771 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(710,771) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(710,771) x common factors =1 x 1 = 1
LCM(710,771) = ( 710 × 771 ) / 1
LCM(710,771) = 547410 / 1
LCM(710,771) = 547410
