Lets's calculate LCM of 420,2845
| 5 | 420, 2845 |
| 84, 569 |
∴ So the LCM of the given numbers is 5 x 84 x 569 = 238980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/238980
Therefore, the GCF of Fractions 5123/420,6720/2845 is 1/238980
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 420,2845 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,2845) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(420,2845) x common factors =5 x 1 = 5
LCM(420,2845) = ( 420 × 2845 ) / 5
LCM(420,2845) = 1194900 / 5
LCM(420,2845) = 238980
