Lets's calculate GCF of 305,793
61 | 305, 793 |
5, 13 |
∴ So the GCF of the given numbers is 61 = 61
Now, list down the factors of 305
:1,5,61,305
Now, list down the factors of 793
:1,13,61,793
Greatest Common Factor
We found the factors 305,793 . The biggest common factor number is the GCF number.
So the greatest common factor 305,793 is 61.
Lets's calculate LCM of 243,843
3 | 243, 843 |
81, 281 |
∴ So the LCM of the given numbers is 3 x 81 x 281 = 68283
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 61/68283
Therefore, the GCF of Fractions 305/243,793/843 is 61/68283
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 243,843 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,843) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(243,843) x common factors =3 x 1 = 3
LCM(243,843) = ( 243 × 843 ) / 3
LCM(243,843) = 204849 / 3
LCM(243,843) = 68283
