How to verify if all elements of a list are equal

Question

I have a result in a list form: {1,2,3,4,5,6}

How to verify if the elements are equal? If I use Equal doesn't works with a list. So, the result is:

`{1,2,3,4,5,6}`

If I use:

Equal[{1,2,3,4,5,6}]

Doesn't works.

How to catch just the numbers, like this?

In[479]:= Equal[1,2,3,4,5,6]

Out[479]= False
