Factors of 9879
List of positive integer factors of 9879 that divides 9879 without a remainder.
1,3,37,89,111,267,3293,9879
Greatest Common Factor
We found the factors 120,9879 . The biggest common factor number is the GCF number.
So the greatest common factor 120,9879 is 3.
Lets's calculate LCM of 30,177
3 | 30, 177 |
10, 59 |
∴ So the LCM of the given numbers is 3 x 10 x 59 = 1770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1770
Therefore, the GCF of Fractions 120/30,9879/177 is 3/1770
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 30,177 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,177) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(30,177) x common factors =3 x 1 = 3
LCM(30,177) = ( 30 × 177 ) / 3
LCM(30,177) = 5310 / 3
LCM(30,177) = 1770
