We found the factors 810,680 . The biggest common factor number is the GCF number.
So the greatest common factor 810,680 is 10.
Lets's calculate LCM of 24,9291
3 | 24, 9291 |
8, 3097 |
∴ So the LCM of the given numbers is 3 x 8 x 3097 = 74328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/74328
Therefore, the GCF of Fractions 810/24,680/9291 is 10/74328
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 24,9291 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,9291) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(24,9291) x common factors =3 x 1 = 3
LCM(24,9291) = ( 24 × 9291 ) / 3
LCM(24,9291) = 222984 / 3
LCM(24,9291) = 74328
