1,19
Factors of 831
List of positive integer factors of 831 that divides 831 without a remainder.
1,3,277,831
Greatest Common Factor
We found the factors 80,19,831 . The biggest common factor number is the GCF number.
So the greatest common factor 80,19,831 is 1.
Lets's calculate LCM of 20,99,928
2 | 20, 99, 928 |
2 | 10, 99, 464 |
5, 99, 232 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 99 x 232 = 459360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/459360
Therefore, the GCF of Fractions 80/20,19/99,831/928 is 1/459360
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 20,99,928 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,99,928) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(20,99,928) x common factors =1 x 4 = 4
LCM(20,99,928) = ( 20 × 99 × 928 ) / 4
LCM(20,99,928) = 1837440 / 4
LCM(20,99,928) = 459360
