1,5,7,35,83,415,581,2905
Greatest Common Factor
We found the factors 485,2905 . The biggest common factor number is the GCF number.
So the greatest common factor 485,2905 is 5.
Lets's calculate LCM of 75,879
3 | 75, 879 |
25, 293 |
∴ So the LCM of the given numbers is 3 x 25 x 293 = 21975
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/21975
Therefore, the GCF of Fractions 485/75,2905/879 is 5/21975
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 75,879 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(75,879) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(75,879) x common factors =3 x 1 = 3
LCM(75,879) = ( 75 × 879 ) / 3
LCM(75,879) = 65925 / 3
LCM(75,879) = 21975
