Lets's calculate GCF of 880,400
2 | 880, 400 |
2 | 440, 200 |
2 | 220, 100 |
2 | 110, 50 |
5 | 55, 25 |
11, 5 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 x 5 = 80
Now, list down the factors of 880
:1,2,4,5,8,10,11,16,20,22,40,44,55,80,88,110,176,220,440,880
Now, list down the factors of 400
:1,2,4,5,8,10,16,20,25,40,50,80,100,200,400
Greatest Common Factor
We found the factors 880,400 . The biggest common factor number is the GCF number.
So the greatest common factor 880,400 is 80.
Lets's calculate LCM of 286,108
2 | 286, 108 |
143, 54 |
∴ So the LCM of the given numbers is 2 x 143 x 54 = 15444
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 80/15444
Therefore, the GCF of Fractions 880/286,400/108 is 80/15444
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 286,108 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(286,108) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(286,108) x common factors =2 x 1 = 2
LCM(286,108) = ( 286 × 108 ) / 2
LCM(286,108) = 30888 / 2
LCM(286,108) = 15444
