Greatest Common Factor
We found the factors 800,553 . The biggest common factor number is the GCF number.
So the greatest common factor 800,553 is 1.
Lets's calculate LCM of 873,861
3 | 873, 861 |
291, 287 |
∴ So the LCM of the given numbers is 3 x 291 x 287 = 250551
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/250551
Therefore, the GCF of Fractions 800/873,553/861 is 1/250551
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 873,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(873,861) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(873,861) x common factors =3 x 1 = 3
LCM(873,861) = ( 873 × 861 ) / 3
LCM(873,861) = 751653 / 3
LCM(873,861) = 250551
