Can the spreadsheet salvage the 991CW

[lrdheat]

Talking of items rarely used, I just noticed that the CW does not find Prime factors of a number like on the EX. Although I rarely use this feature, it is curious that it is not supported by the CW. The 9750 giii and the fx-CG 50 also do not find factors. Oddly, all of these calculators find LCM’s and GCM’s.
