Greatest Common Factor
We found the factors 231,143 . The biggest common factor number is the GCF number.
So the greatest common factor 231,143 is 11.
Lets's calculate LCM of 327,447
3 | 327, 447 |
109, 149 |
∴ So the LCM of the given numbers is 3 x 109 x 149 = 48723
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/48723
Therefore, the GCF of Fractions 231/327,143/447 is 11/48723
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 327,447 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(327,447) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(327,447) x common factors =3 x 1 = 3
LCM(327,447) = ( 327 × 447 ) / 3
LCM(327,447) = 146169 / 3
LCM(327,447) = 48723
