### Tall brace in multi line math expression.

I need a small help from this forum.

I have a math expression spanning many lines (a continued fraction) :

\begin{equation}
1+
\cfrac {1}{1+
\cfrac {1}{1+
\cfrac {1}{1+
\cfrac {1}{1+
\cfrac {1}{1+ \dots
}}}}}
\end{equation}

I would like to add a tall curly brace } spanning the entire expression
to the right of the expression. Can I do it with \right\} ? Where do I
put this command ? Any other way to do this ?

In fact, I want a tall } and = xyz on the right side of the above
expression (see https://drpartha.org.in/drpartha/tall-brace-right.png

### Tall brace in multi line math expression.

Something like
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
\left.
\begin{aligned}
1 + \cfrac{1}{1+
\cfrac {1}{1+
\cfrac {1}{1+
\cfrac {1}{1+
\cfrac {1}{1+ \dotsb
}}}}}
\end{aligned}
\right\} = xyz
\end{equation}
\end{document}


should do it. The "aligned" environment is to eliminate the extra vertical space above the fraction.

### Tall brace in multi line math expression.

Another way to achieve the same result is to use the '\left.' and '\right\}' commands together.
\begin{equation}
1+
\cfrac {1}{1+
\cfrac {1}{1+
\cfrac {1}{1+
\cfrac {1}{1+
\cfrac {1}{1+ \dots
\left.
\right\}
}}}}}
\end{equation}
