Question: how to map a function to a list, where the function takes more than one argument?

One can do igcd(12,8), and igcd(16,3), etc...

But how to define a list/set/array/vector/matrix, etc... that contains these pair of numbers, and then call/map igcd on this list?

I tried putting the pair of values in a list and set and even a matrix, calling calling map(igcd, lst) but not getting it right.

The confusing part for me with Maple is to know which data structure to use for each function, since there are more than one. Here are my silly attempts:




I was looking for something like in Mathematica:

lst = {{12, 8}, {16, 3}};
GCD @@ lst

    {4, 1}

I am sure it is possible to do this in Maple (i.e. map igcd to list of pair of numbers), I just can't get the syntax right. I did look at few examples somewhat related, but did not understand what they are doing. They said I need to pass an extra argument for map in this case?

thank you
