So the greatest common factor 642,582,836 is 2.
Lets's calculate LCM of 24,70,408
2 | 24, 70, 408 |
2 | 12, 35, 204 |
2 | 6, 35, 102 |
3 | 3, 35, 51 |
1, 35, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 1 x 35 x 17 = 14280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/14280
Therefore, the GCF of Fractions 642/24,582/70,836/408 is 2/14280
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 24,70,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,70,408) = 2
common factors(in case of two or more numbers have common factors) = 24
GCF(24,70,408) x common factors =2 x 24 = 48
LCM(24,70,408) = ( 24 × 70 × 408 ) / 48
LCM(24,70,408) = 685440 / 48
LCM(24,70,408) = 14280
