So the greatest common factor 728,426 is 2.
Lets's calculate LCM of 342,717
3 | 342, 717 |
114, 239 |
∴ So the LCM of the given numbers is 3 x 114 x 239 = 81738
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/81738
Therefore, the GCF of Fractions 728/342,426/717 is 2/81738
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 342,717 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(342,717) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(342,717) x common factors =3 x 1 = 3
LCM(342,717) = ( 342 × 717 ) / 3
LCM(342,717) = 245214 / 3
LCM(342,717) = 81738
