The smallest and largest common factor of numbers

[alireza]

Hi, I wanted to enter two items for my calculator, one is the smallest common factor and the other is the largest common factor or GCD LCM. Please help me with your page image and its blocks. I really need it.

How do I calculate LCM?

I got a recursive solution, and an extension to lists of numbers ... [gcd] [gcd_test] [lcm] [lcm_test] (I left out validation, for simplicity) And here is the list based solution ... [lcm_list] [lcm_list_test] [max] [min] The procedures are draggable, the tests not draggable. The .aia and blocks: [blocks] lcm.aia (5.0 KB) P.S. Thank you for a fun question!
