So the greatest common factor 563,455 is 1.
Lets's calculate LCM of 918,723
3 | 918, 723 |
306, 241 |
∴ So the LCM of the given numbers is 3 x 306 x 241 = 221238
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/221238
Therefore, the GCF of Fractions 563/918,455/723 is 1/221238
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 918,723 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(918,723) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(918,723) x common factors =3 x 1 = 3
LCM(918,723) = ( 918 × 723 ) / 3
LCM(918,723) = 663714 / 3
LCM(918,723) = 221238
