Prime Factorization

In the COMP Mode, you can factor a positive integer up to 10 digits into
prime factors up to three digits.
To perform prime factorization on 1014
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.
To perform prime factorization on 4104676 (= 2
Any one of the following operations will exit prime factorization result
display.
• Pressing !e(FACT) or =.
• Pressing any of the following keys: . or e.
• 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.
