Frequently Asked Questions
Prime Factorization
In the COMP Mode, a positive integer no more than 10 digits long can be factored to prime factors.
Example 1: To perform prime factorization on 1014
- 1014
- 1014
(FACT)
When you perform prime factorization on a value that includes a factor that is prime number with more than three digits, the part that cannot be factored will be enclosed in parentheses on the display.
Example 2: To perform prime factorization on 4104676 (= 22 × 10132)
- 4104676
- 4104676
- (FACT)
Any one of the following operations will exit prime factorization result display.
- Pressing (FACT) or .
- Pressing any of the following keys: 
or .
- Using the setup menu to change the angle unit setting (Deg, Rad, Gra) or the display digits setting (Fix, Sci, Norm).
Note
You will not be able to execute prime factorization while a decimal value, fraction, or negative value calculation result is displayed. Trying to do so will cause a math error (Math ERROR).
You will not be able to execute prime factorization while the result of a calculation that uses Pol, Rec is displayed.
