:1,661
Now, list down the factors of 230
:1,2,5,10,23,46,115,230
Greatest Common Factor
We found the factors 661,230 . The biggest common factor number is the GCF number.
So the greatest common factor 661,230 is 1.
Lets's calculate LCM of 485,845
5 | 485, 845 |
97, 169 |
∴ So the LCM of the given numbers is 5 x 97 x 169 = 81965
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/81965
Therefore, the GCF of Fractions 661/485,230/845 is 1/81965
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 485,845 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(485,845) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(485,845) x common factors =5 x 1 = 5
LCM(485,845) = ( 485 × 845 ) / 5
LCM(485,845) = 409825 / 5
LCM(485,845) = 81965
