1,8887
Greatest Common Factor
We found the factors 687,8887 . The biggest common factor number is the GCF number.
So the greatest common factor 687,8887 is 1.
Lets's calculate LCM of 792,408
2 | 792, 408 |
2 | 396, 204 |
2 | 198, 102 |
3 | 99, 51 |
33, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 33 x 17 = 13464
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13464
Therefore, the GCF of Fractions 687/792,8887/408 is 1/13464
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 792,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(792,408) = 24
common factors(in case of two or more numbers have common factors) = 1
GCF(792,408) x common factors =24 x 1 = 24
LCM(792,408) = ( 792 × 408 ) / 24
LCM(792,408) = 323136 / 24
LCM(792,408) = 13464
