Greatest Common Factor
We found the factors 858,869 . The biggest common factor number is the GCF number.
So the greatest common factor 858,869 is 11.
Lets's calculate LCM of 164,806
2 | 164, 806 |
82, 403 |
∴ So the LCM of the given numbers is 2 x 82 x 403 = 66092
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/66092
Therefore, the GCF of Fractions 858/164,869/806 is 11/66092
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 164,806 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(164,806) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(164,806) x common factors =2 x 1 = 2
LCM(164,806) = ( 164 × 806 ) / 2
LCM(164,806) = 132184 / 2
LCM(164,806) = 66092
