So the greatest common factor 871,705 is 1.
Lets's calculate LCM of 855,231
3 | 855, 231 |
285, 77 |
∴ So the LCM of the given numbers is 3 x 285 x 77 = 65835
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/65835
Therefore, the GCF of Fractions 871/855,705/231 is 1/65835
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 855,231 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(855,231) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(855,231) x common factors =3 x 1 = 3
LCM(855,231) = ( 855 × 231 ) / 3
LCM(855,231) = 197505 / 3
LCM(855,231) = 65835
