So the greatest common factor 418,680 is 2.
Lets's calculate LCM of 318,717
3 | 318, 717 |
106, 239 |
∴ So the LCM of the given numbers is 3 x 106 x 239 = 76002
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/76002
Therefore, the GCF of Fractions 418/318,680/717 is 2/76002
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 318,717 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(318,717) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(318,717) x common factors =3 x 1 = 3
LCM(318,717) = ( 318 × 717 ) / 3
LCM(318,717) = 228006 / 3
LCM(318,717) = 76002
