Lets's calculate GCF of 480,800
2 | 480, 800 |
2 | 240, 400 |
2 | 120, 200 |
2 | 60, 100 |
2 | 30, 50 |
5 | 15, 25 |
3, 5 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 x 2 x 5 = 160
Now, list down the factors of 480
:1,2,3,4,5,6,8,10,12,15,16,20,24,30,32,40,48,60,80,96,120,160,240,480
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 480,800 . The biggest common factor number is the GCF number.
So the greatest common factor 480,800 is 160.
Lets's calculate LCM of 13,687
Given numbers has no common factors except 1. So, there LCM is their product i.e 8931
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 160/8931
Therefore, the GCF of Fractions 480/13,800/687 is 160/8931
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 13,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,687) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(13,687) x common factors =1 x 1 = 1
LCM(13,687) = ( 13 × 687 ) / 1
LCM(13,687) = 8931 / 1
LCM(13,687) = 8931
