What are all sets of four numbers that multiply to give 36? Thanks! Just want to make sure I haven't missed out on any.

A={1,2,3,6}
A= The set of all of four numbers that multiply to give 36

All you got to do is to factor out 36 and it's a nice thing that 36 factors out in 4 factors (don't ever underestimate 1 ). So, you're done, just write out the factors with commas between them and within a curly brackets.

I hope you meant four whole numbers, else there would be infinitely many sets.

It also depends if the numbers have to be unique. If not, you could have:
1,1,1,36
1,1,2,18
2,2,3,3
etc.
