LESS - multiple different classes with the same st

Question

How would you write this style below in LESS?

nav a:hover,
nav a:focus,
footer a:hover,
footer a:focus,
.fullscreen-container a:hover,
.fullscreen-container a:focus {
    text-decoration: none;
}

My attempt:

.text-decoration-none () {
    text-decoration: none;
}

nav a {
    &:focus,
    &:focus {
        .text-decoration-none ();
    }
}

footer a {
    &:focus,
    &:focus {
        .text-decoration-none ();
    }
}

.fullscreen-container a {
    &:focus,
    &:focus {
        .text-decoration-none ();
    }
}

Result:

nav a:focus,
nav a:focus {
  text-decoration: none;
}
footer a:focus,
footer a:focus {
  text-decoration: none;
}
.fullscreen-container a:focus,
.fullscreen-container a:focus {
  text-decoration: none;
}

Ideal result:

nav a:hover,
nav a:focus,
footer a:hover,
footer a:focus,
.fullscreen-container a:hover,
.fullscreen-container a:focus {
    text-decoration: none;
}

Any ideas?
