Now, list down the factors of 300
:1,2,3,4,5,6,10,12,15,20,25,30,50,60,75,100,150,300
Greatest Common Factor
We found the factors 13,790,300 . The biggest common factor number is the GCF number.
So the greatest common factor 13,790,300 is 1.
Lets's calculate LCM of 20,34,569
2 | 20, 34, 569 |
10, 17, 569 |
∴ So the LCM of the given numbers is 2 x 10 x 17 x 569 = 193460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/193460
Therefore, the GCF of Fractions 13/20,790/34,300/569 is 1/193460
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 20,34,569 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,34,569) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(20,34,569) x common factors =1 x 2 = 2
LCM(20,34,569) = ( 20 × 34 × 569 ) / 2
LCM(20,34,569) = 386920 / 2
LCM(20,34,569) = 193460
