So the greatest common factor 312,655 is 1.
Lets's calculate LCM of 831,198
3 | 831, 198 |
277, 66 |
∴ So the LCM of the given numbers is 3 x 277 x 66 = 54846
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54846
Therefore, the GCF of Fractions 312/831,655/198 is 1/54846
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 831,198 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(831,198) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(831,198) x common factors =3 x 1 = 3
LCM(831,198) = ( 831 × 198 ) / 3
LCM(831,198) = 164538 / 3
LCM(831,198) = 54846
