Greatest Common Factor
We found the factors 660,396 . The biggest common factor number is the GCF number.
So the greatest common factor 660,396 is 132.
Lets's calculate LCM of 30,2427
3 | 30, 2427 |
10, 809 |
∴ So the LCM of the given numbers is 3 x 10 x 809 = 24270
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 132/24270
Therefore, the GCF of Fractions 660/30,396/2427 is 132/24270
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 30,2427 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,2427) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(30,2427) x common factors =3 x 1 = 3
LCM(30,2427) = ( 30 × 2427 ) / 3
LCM(30,2427) = 72810 / 3
LCM(30,2427) = 24270
