So the greatest common factor 51,58,578 is 1.
Lets's calculate LCM of 998,998,442
2 | 998, 998, 442 |
499 | 499, 499, 221 |
1, 1, 221 |
∴ So the LCM of the given numbers is 2 x 499 x 1 x 1 x 221 = 220558
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/220558
Therefore, the GCF of Fractions 51/998,58/998,578/442 is 1/220558
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 998,998,442 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(998,998,442) = 2
common factors(in case of two or more numbers have common factors) = 998
GCF(998,998,442) x common factors =2 x 998 = 1996
LCM(998,998,442) = ( 998 × 998 × 442 ) / 1996
LCM(998,998,442) = 440233768 / 1996
LCM(998,998,442) = 220558
