So the greatest common factor 611,687 is 1.
Lets's calculate LCM of 817,589
19 | 817, 589 |
43, 31 |
∴ So the LCM of the given numbers is 19 x 43 x 31 = 25327
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25327
Therefore, the GCF of Fractions 611/817,687/589 is 1/25327
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 817,589 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(817,589) = 19
common factors(in case of two or more numbers have common factors) = 1
GCF(817,589) x common factors =19 x 1 = 19
LCM(817,589) = ( 817 × 589 ) / 19
LCM(817,589) = 481213 / 19
LCM(817,589) = 25327
