So the greatest common factor 308,759 is 11.
Lets's calculate LCM of 140,275
5 | 140, 275 |
28, 55 |
∴ So the LCM of the given numbers is 5 x 28 x 55 = 7700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/7700
Therefore, the GCF of Fractions 308/140,759/275 is 11/7700
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 140,275 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(140,275) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(140,275) x common factors =5 x 1 = 5
LCM(140,275) = ( 140 × 275 ) / 5
LCM(140,275) = 38500 / 5
LCM(140,275) = 7700
