:1,3,9,109,327,981
Greatest Common Factor
We found the factors 765,981 . The biggest common factor number is the GCF number.
So the greatest common factor 765,981 is 9.
Lets's calculate LCM of 18,4056
2 | 18, 4056 |
3 | 9, 2028 |
3, 676 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 676 = 12168
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/12168
Therefore, the GCF of Fractions 765/18,981/4056 is 9/12168
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 18,4056 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,4056) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(18,4056) x common factors =6 x 1 = 6
LCM(18,4056) = ( 18 × 4056 ) / 6
LCM(18,4056) = 73008 / 6
LCM(18,4056) = 12168
