So the greatest common factor 620,306 is 2.
Lets's calculate LCM of 808,286
2 | 808, 286 |
404, 143 |
∴ So the LCM of the given numbers is 2 x 404 x 143 = 115544
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/115544
Therefore, the GCF of Fractions 620/808,306/286 is 2/115544
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 808,286 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(808,286) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(808,286) x common factors =2 x 1 = 2
LCM(808,286) = ( 808 × 286 ) / 2
LCM(808,286) = 231088 / 2
LCM(808,286) = 115544
