Prime Factorization on Casio CLASSWIZ emulator somehow gave result as prime for (191373191) whereas HP 12C prime factor program result 1237 x 15467

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.

Hello Joe Horn

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

Both results are wrong. 191373191 is not prime, it is 12373 x 15467.
Which 12C program returns 1237 and 15467 as prime factors? Or was this just a typo?

He might have been referring to my program, 1237 is a typo.

Sorry guys that was a typo
191373191 = 12373 and 15467
