So the greatest common factor 809,249 is 1.
Lets's calculate LCM of 561,255
3 | 561, 255 |
17 | 187, 85 |
11, 5 |
∴ So the LCM of the given numbers is 3 x 17 x 11 x 5 = 2805
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2805
Therefore, the GCF of Fractions 809/561,249/255 is 1/2805
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 561,255 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(561,255) = 51
common factors(in case of two or more numbers have common factors) = 1
GCF(561,255) x common factors =51 x 1 = 51
LCM(561,255) = ( 561 × 255 ) / 51
LCM(561,255) = 143055 / 51
LCM(561,255) = 2805
