So the greatest common factor 309,803 is 1.
Lets's calculate LCM of 246,987
3 | 246, 987 |
82, 329 |
∴ So the LCM of the given numbers is 3 x 82 x 329 = 80934
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/80934
Therefore, the GCF of Fractions 309/246,803/987 is 1/80934
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 246,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(246,987) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(246,987) x common factors =3 x 1 = 3
LCM(246,987) = ( 246 × 987 ) / 3
LCM(246,987) = 242802 / 3
LCM(246,987) = 80934
