I'm using Casio fx-991MS do I want to change any mode because it is not working for me !😢

[@ahsing_math]

Hi. 991MS and 991EX are two different models ya. This Short is for 991EX.
May consider these videos:
1. factorization method: ruclips.net/video/WIy-qwoGSco/видео.html
2. Euclidean algorithm: ruclips.net/video/oDVLU7m4vmA/видео.html
Hope they help.
Thanks for watching and have a nice day.

I picked the 1-COMP mode, and it works.

This didn’t work for me.. can you try HCF for 36 & 54

[@ahsing_math]

Hi. Using the same method, I obtained 36=2²×3² and 54=2×3³, then with all common factors, yields 2×3²=18.
Thanks for watching and have a nice day.
