We found the factors 268,240 . The biggest common factor number is the GCF number.
So the greatest common factor 268,240 is 4.
Lets's calculate LCM of 687,243
3 | 687, 243 |
229, 81 |
∴ So the LCM of the given numbers is 3 x 229 x 81 = 55647
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/55647
Therefore, the GCF of Fractions 268/687,240/243 is 4/55647
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 687,243 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,243) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(687,243) x common factors =3 x 1 = 3
LCM(687,243) = ( 687 × 243 ) / 3
LCM(687,243) = 166941 / 3
LCM(687,243) = 55647
