Lets's calculate LCM of 856,284
2 | 856, 284 |
2 | 428, 142 |
214, 71 |
∴ So the LCM of the given numbers is 2 x 2 x 214 x 71 = 60776
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/60776
Therefore, the GCF of Fractions 470/856,320/284 is 10/60776
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 856,284 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(856,284) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(856,284) x common factors =4 x 1 = 4
LCM(856,284) = ( 856 × 284 ) / 4
LCM(856,284) = 243104 / 4
LCM(856,284) = 60776
