Lets's calculate LCM of 255,2517
3 | 255, 2517 |
85, 839 |
∴ So the LCM of the given numbers is 3 x 85 x 839 = 213945
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/213945
Therefore, the GCF of Fractions 724/255,8484/2517 is 4/213945
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 255,2517 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(255,2517) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(255,2517) x common factors =3 x 1 = 3
LCM(255,2517) = ( 255 × 2517 ) / 3
LCM(255,2517) = 641835 / 3
LCM(255,2517) = 213945
