So the greatest common factor 687,759 is 3.
Lets's calculate LCM of 66,6149
11 | 66, 6149 |
6, 559 |
∴ So the LCM of the given numbers is 11 x 6 x 559 = 36894
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/36894
Therefore, the GCF of Fractions 687/66,759/6149 is 3/36894
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 66,6149 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(66,6149) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(66,6149) x common factors =11 x 1 = 11
LCM(66,6149) = ( 66 × 6149 ) / 11
LCM(66,6149) = 405834 / 11
LCM(66,6149) = 36894
