So the greatest common factor 845,765 is 5.
Lets's calculate LCM of 30,9424
2 | 30, 9424 |
15, 4712 |
∴ So the LCM of the given numbers is 2 x 15 x 4712 = 141360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/141360
Therefore, the GCF of Fractions 845/30,765/9424 is 5/141360
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 30,9424 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,9424) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(30,9424) x common factors =2 x 1 = 2
LCM(30,9424) = ( 30 × 9424 ) / 2
LCM(30,9424) = 282720 / 2
LCM(30,9424) = 141360
