Factors of 8911
List of positive integer factors of 8911 that divides 8911 without a remainder.
1,7,19,67,133,469,1273,8911
Greatest Common Factor
We found the factors 515,8911 . The biggest common factor number is the GCF number.
So the greatest common factor 515,8911 is 1.
Lets's calculate LCM of 490,455
5 | 490, 455 |
7 | 98, 91 |
14, 13 |
∴ So the LCM of the given numbers is 5 x 7 x 14 x 13 = 6370
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6370
Therefore, the GCF of Fractions 515/490,8911/455 is 1/6370
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 490,455 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,455) = 35
common factors(in case of two or more numbers have common factors) = 1
GCF(490,455) x common factors =35 x 1 = 35
LCM(490,455) = ( 490 × 455 ) / 35
LCM(490,455) = 222950 / 35
LCM(490,455) = 6370
