So the greatest common factor 816,745 is 1.
Lets's calculate LCM of 512,686
2 | 512, 686 |
256, 343 |
∴ So the LCM of the given numbers is 2 x 256 x 343 = 175616
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/175616
Therefore, the GCF of Fractions 816/512,745/686 is 1/175616
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 512,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(512,686) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(512,686) x common factors =2 x 1 = 2
LCM(512,686) = ( 512 × 686 ) / 2
LCM(512,686) = 351232 / 2
LCM(512,686) = 175616
