Greatest Common Factor
We found the factors 272,879 . The biggest common factor number is the GCF number.
So the greatest common factor 272,879 is 1.
Lets's calculate LCM of 765,831
3 | 765, 831 |
255, 277 |
∴ So the LCM of the given numbers is 3 x 255 x 277 = 211905
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/211905
Therefore, the GCF of Fractions 272/765,879/831 is 1/211905
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 765,831 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(765,831) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(765,831) x common factors =3 x 1 = 3
LCM(765,831) = ( 765 × 831 ) / 3
LCM(765,831) = 635715 / 3
LCM(765,831) = 211905
