Lets's calculate GCF of 240,800
2 | 240, 800 |
2 | 120, 400 |
2 | 60, 200 |
2 | 30, 100 |
5 | 15, 50 |
3, 10 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 x 5 = 80
Now, list down the factors of 240
:1,2,3,4,5,6,8,10,12,15,16,20,24,30,40,48,60,80,120,240
Now, list down the factors of 800
:1,2,4,5,8,10,16,20,25,32,40,50,80,100,160,200,400,800
Greatest Common Factor
We found the factors 240,800 . The biggest common factor number is the GCF number.
So the greatest common factor 240,800 is 80.
Lets's calculate LCM of 40,344
2 | 40, 344 |
2 | 20, 172 |
2 | 10, 86 |
5, 43 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 43 = 1720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 80/1720
Therefore, the GCF of Fractions 240/40,800/344 is 80/1720
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 40,344 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,344) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(40,344) x common factors =8 x 1 = 8
LCM(40,344) = ( 40 × 344 ) / 8
LCM(40,344) = 13760 / 8
LCM(40,344) = 1720
