So the greatest common factor 324,355 is 1.
Lets's calculate LCM of 858,909
3 | 858, 909 |
286, 303 |
∴ So the LCM of the given numbers is 3 x 286 x 303 = 259974
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/259974
Therefore, the GCF of Fractions 324/858,355/909 is 1/259974
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 858,909 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(858,909) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(858,909) x common factors =3 x 1 = 3
LCM(858,909) = ( 858 × 909 ) / 3
LCM(858,909) = 779922 / 3
LCM(858,909) = 259974
