RE: Prime Factor  Casio Classwiz VS HP 12C
The manual for the Casio says that it cannot factor a value if "two or more of the prime factors of the value have more than three digits". The display will indicate when factoring is incomplete: "The part that cannot be factored will be enclosed in parentheses on the display."
Try factoring 1009^2. According to the manual, it should fail to factor. <0ɸ0> Joe

Hello Joe Horn
Interesting to know that the maximum 3 digits prime for Casio Classwiz is it limit otherwise all other features is excellent. Gamo

Which 12C program returns 1237 and 15467 as prime factors? Or was this just a typo? Dieter
