Greatest Common Factor
We found the factors 717,821 . The biggest common factor number is the GCF number.
So the greatest common factor 717,821 is 1.
Lets's calculate LCM of 487,849
Given numbers has no common factors except 1. So, there LCM is their product i.e 413463
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/413463
Therefore, the GCF of Fractions 717/487,821/849 is 1/413463
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 487,849 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(487,849) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(487,849) x common factors =1 x 1 = 1
LCM(487,849) = ( 487 × 849 ) / 1
LCM(487,849) = 413463 / 1
LCM(487,849) = 413463
