How to collect a fraction in a certain equation?

Suppose i have this equation :

>> syms a b c d e
>> f=(a/3)+(b/3)+(c/3)+(d/3)+(e/3)

f =

1/3*a+1/3*b+1/3*c+1/3*d+1/3*e

And i need some command to collect term. And i wish it will displays :

f =

(1/3)*(a+b+c+d+e)

Is it possible to do this? How?

Thanks in advance!

Hi Fahmy.

I try the matlab function factor, but it get the result as following.

syms a b c d e
f=(a/3)+(b/3)+(c/3)+(d/3)+(e/3);
F=factor(f)

F=[1/3,a+b+c+d+e]. maybe exist another method.

Anyway, it's still great. Thanks.
