Lets's calculate LCM of 585,480
3 | 585, 480 |
5 | 195, 160 |
39, 32 |
∴ So the LCM of the given numbers is 3 x 5 x 39 x 32 = 18720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18720
Therefore, the GCF of Fractions 421/585,272/480 is 1/18720
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 585,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(585,480) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(585,480) x common factors =15 x 1 = 15
LCM(585,480) = ( 585 × 480 ) / 15
LCM(585,480) = 280800 / 15
LCM(585,480) = 18720
