Factors of 7889
List of positive integer factors of 7889 that divides 7889 without a remainder.
1,7,23,49,161,343,1127,7889
Greatest Common Factor
We found the factors 471,7889 . The biggest common factor number is the GCF number.
So the greatest common factor 471,7889 is 1.
Lets's calculate LCM of 309,105
3 | 309, 105 |
103, 35 |
∴ So the LCM of the given numbers is 3 x 103 x 35 = 10815
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10815
Therefore, the GCF of Fractions 471/309,7889/105 is 1/10815
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 309,105 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(309,105) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(309,105) x common factors =3 x 1 = 3
LCM(309,105) = ( 309 × 105 ) / 3
LCM(309,105) = 32445 / 3
LCM(309,105) = 10815
