So the greatest common factor 168,434 is 14.
Lets's calculate LCM of 993,945
3 | 993, 945 |
331, 315 |
∴ So the LCM of the given numbers is 3 x 331 x 315 = 312795
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/312795
Therefore, the GCF of Fractions 168/993,434/945 is 14/312795
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 993,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(993,945) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(993,945) x common factors =3 x 1 = 3
LCM(993,945) = ( 993 × 945 ) / 3
LCM(993,945) = 938385 / 3
LCM(993,945) = 312795
