So the greatest common factor 518,486 is 2.
Lets's calculate LCM of 288,802
2 | 288, 802 |
144, 401 |
∴ So the LCM of the given numbers is 2 x 144 x 401 = 115488
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/115488
Therefore, the GCF of Fractions 518/288,486/802 is 2/115488
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 288,802 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(288,802) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(288,802) x common factors =2 x 1 = 2
LCM(288,802) = ( 288 × 802 ) / 2
LCM(288,802) = 230976 / 2
LCM(288,802) = 115488
