Below you will find the code, to input into your calculator to create the prime factorization program. If you don’t know how to start a new program on your Casio graphing calculator, click <here>. Below the code, you will find detailed instructions on how to use the program.

Prime Factorization Program Code

All of the characters typed in this program can be accessed by pressing the [SHIFT] [PRGM] and [OPTN] keys in the programming app on your Casio calculator. The Image below is the code. Enter exactly what is seen in the image. (Sorry for the stitched together image. The Casio fx-9750GII doesn’t let you connect to the computer.)

How To Use The Prime Factorization Program

---

To start off, press [MENU]  and then scroll to the “prgm” app and press [EXE]. After you have done that you will be at the screen below. (If you don’t see this screen just press [EXIT] a couple of times.)

Then, scroll to “PRIMEFCT”, or whatever you named your program, and press [EXE]. This will start the program and you will be prompted to enter the number you wish to factor, as seen below.

Simply enter the number you would like to factor and press [EXE]

Now you should see the first prime factor of your original number (as seen above). Continue pressing [EXE] and each time you do, the program will spit out the next prime factor.

Keep pressing [EXE] until the program has shown all of the prime factors of the number you entered. (you will know when you have reached the end because the program will display “DONE”

Now you can see the program gave all the prime factors of my example number 318.
