1,2,3,4,6,8,12,16,24,32,48,64,96,128,192,384
Factors of 871
List of positive integer factors of 871 that divides 871 without a remainder.
1,13,67,871
Greatest Common Factor
We found the factors 68,384,871 . The biggest common factor number is the GCF number.
So the greatest common factor 68,384,871 is 1.
Lets's calculate LCM of 24,10,280
2 | 24, 10, 280 |
2 | 12, 5, 140 |
2 | 6, 5, 70 |
5 | 3, 5, 35 |
3, 1, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 3 x 1 x 7 = 840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/840
Therefore, the GCF of Fractions 68/24,384/10,871/280 is 1/840
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 24,10,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,10,280) = 2
common factors(in case of two or more numbers have common factors) = 40
GCF(24,10,280) x common factors =2 x 40 = 80
LCM(24,10,280) = ( 24 × 10 × 280 ) / 80
LCM(24,10,280) = 67200 / 80
LCM(24,10,280) = 840
