Prime factorization Casio 35+ Ell

Question

Hello, How can we perform the prime factorization of a number on the Casio graph 35+ E II? Thank you.

Not a very interesting comment (some might say "condescending"). Indeed, there are such functions on Casio calculators designed for middle school (unfortunately not on the graphing ones).
The solution is still to create a program and enter it into the calculator, or to find a ready-made one online...

Hello,  We do it like on all calculators: we divide the given number by all the prime numbers starting from the smallest (2, 3, 5, 7, 11, 13, etc).

I didn't find it.

Pierr10 · Answer

It's a scientific calculator with a lot of possibilities.
It is not designed to perform prime factor decompositions, which are middle school exercises.
On the other hand, the GCD and LCM functions are implemented. But the results are certainly not provided in the form of products of prime numbers. Once again, this is not a machine for middle school students.

Fab · Answer

Reducing prime factorization to a middle school level is quite limiting. It is useful at all levels (it is even surprising that it is taught in middle school, as you will encounter the famous Fundamental Theorem of Arithmetic even in preparatory classes, and that’s where it is truly addressed—so the real level is here). A higher-level calculator should have more features, not lose them.
