Greatest Common Factor
We found the factors 331,623 . The biggest common factor number is the GCF number.
So the greatest common factor 331,623 is 1.
Lets's calculate LCM of 831,309
3 | 831, 309 |
277, 103 |
∴ So the LCM of the given numbers is 3 x 277 x 103 = 85593
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/85593
Therefore, the GCF of Fractions 331/831,623/309 is 1/85593
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 831,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(831,309) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(831,309) x common factors =3 x 1 = 3
LCM(831,309) = ( 831 × 309 ) / 3
LCM(831,309) = 256779 / 3
LCM(831,309) = 85593
