1,2,3,4,5,6,7,10,12,14,15,20,21,25,28,30,35,42,50,60,70,75,84,100,105,140,150,175,210,300,350,420,525,700,1050,2100
Factors of 2489
List of positive integer factors of 2489 that divides 2489 without a remainder.
1,19,131,2489
Greatest Common Factor
We found the factors 2100,2489 . The biggest common factor number is the GCF number.
So the greatest common factor 2100,2489 is 1.
Lets's calculate LCM of 65,845
5 | 65, 845 |
13 | 13, 169 |
1, 13 |
∴ So the LCM of the given numbers is 5 x 13 x 1 x 13 = 845
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/845
Therefore, the GCF of Fractions 2100/65,2489/845 is 1/845
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 65,845 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,845) = 65
common factors(in case of two or more numbers have common factors) = 1
GCF(65,845) x common factors =65 x 1 = 65
LCM(65,845) = ( 65 × 845 ) / 65
LCM(65,845) = 54925 / 65
LCM(65,845) = 845
