Greatest Common Factor
We found the factors and prime factorization of 72, 54 and 18. The biggest common factor number is the GCF number.
So the greatest common factor 72, 54 and 18 is 18.

Step-by-step explanation:
Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
The two points are C(2,-1) and D(5,3). Using the distance formula, we get
![CD=\sqrt{(5-2)^2+(3-(-1))^2}](https://tex.z-dn.net/?f=CD%3D%5Csqrt%7B%285-2%29%5E2%2B%283-%28-1%29%29%5E2%7D)
![CD=\sqrt{(3)^2+(3+1)^2}](https://tex.z-dn.net/?f=CD%3D%5Csqrt%7B%283%29%5E2%2B%283%2B1%29%5E2%7D)
![CD=\sqrt{(3)^2+4^2}](https://tex.z-dn.net/?f=CD%3D%5Csqrt%7B%283%29%5E2%2B4%5E2%7D)
On further simplification, we get
![CD=\sqrt{9+16}](https://tex.z-dn.net/?f=CD%3D%5Csqrt%7B9%2B16%7D)
![CD=\sqrt{25}](https://tex.z-dn.net/?f=CD%3D%5Csqrt%7B25%7D)
![CD=5](https://tex.z-dn.net/?f=CD%3D5)
The distance from point C to D is 5 units. Therefore, the correct option is A.
