1,2,3,4,6,8,12,16,24,32,48,64,96,128,192,256,384,768
Greatest Common Factor
We found the factors 393,103,768 . The biggest common factor number is the GCF number.
So the greatest common factor 393,103,768 is 1.
Lets's calculate LCM of 75,15,90
3 | 75, 15, 90 |
5 | 25, 5, 30 |
1, 5, 6 |
∴ So the LCM of the given numbers is 3 x 5 x 1 x 5 x 6 = 450
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/450
Therefore, the GCF of Fractions 393/75,103/15,768/90 is 1/450
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 75,15,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(75,15,90) = 15
common factors(in case of two or more numbers have common factors) = 15
GCF(75,15,90) x common factors =15 x 15 = 225
LCM(75,15,90) = ( 75 × 15 × 90 ) / 225
LCM(75,15,90) = 101250 / 225
LCM(75,15,90) = 450
