Lets's calculate LCM of 408,697
17 | 408, 697 |
24, 41 |
∴ So the LCM of the given numbers is 17 x 24 x 41 = 16728
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16728
Therefore, the GCF of Fractions 676/408,193/697 is 1/16728
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 408,697 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(408,697) = 17
common factors(in case of two or more numbers have common factors) = 1
GCF(408,697) x common factors =17 x 1 = 17
LCM(408,697) = ( 408 × 697 ) / 17
LCM(408,697) = 284376 / 17
LCM(408,697) = 16728
