Greatest Common Factor
We found the factors 306,830 . The biggest common factor number is the GCF number.
So the greatest common factor 306,830 is 2.
Lets's calculate LCM of 518,978
2 | 518, 978 |
259, 489 |
∴ So the LCM of the given numbers is 2 x 259 x 489 = 253302
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/253302
Therefore, the GCF of Fractions 306/518,830/978 is 2/253302
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 518,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(518,978) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(518,978) x common factors =2 x 1 = 2
LCM(518,978) = ( 518 × 978 ) / 2
LCM(518,978) = 506604 / 2
LCM(518,978) = 253302
