Lets's calculate LCM of 518,686
2 | 518, 686 |
7 | 259, 343 |
37, 49 |
∴ So the LCM of the given numbers is 2 x 7 x 37 x 49 = 25382
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25382
Therefore, the GCF of Fractions 863/518,561/686 is 1/25382
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 518,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(518,686) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(518,686) x common factors =14 x 1 = 14
LCM(518,686) = ( 518 × 686 ) / 14
LCM(518,686) = 355348 / 14
LCM(518,686) = 25382
