Prime Factor - Casio Classwiz VS HP 12C - Gamo - 08-21-2017 01:42 AM
Prime Factorization on Casio CLASSWIZ emulator somehow gave result as prime for (191373191) whereas HP 12C prime factor program result 1237 x 15467 Gamo RE: Prime Factor - Casio Classwiz VS HP 12C - Joe Horn - 08-21-2017 02:10 AM
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. RE: Prime Factor - Casio Classwiz VS HP 12C - Gamo - 08-21-2017 09:23 AM
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 RE: Prime Factor - Casio Classwiz VS HP 12C - Dieter - 08-21-2017 10:37 AM

Which 12C program returns 1237 and 15467 as prime factors? Or was this just a typo? Dieter RE: Prime Factor - Casio Classwiz VS HP 12C - Don Shepherd - 08-21-2017 12:47 PM
