How many facebook friends does it take to have a mutual friend with every user on facebook?

[Charles In Charge]

What would be the minimum number? I know facebook is always adding/losing new accounts, so lets use the facebook statistics webpage where they list;

Number of users = 500,000,000 and the average user has 130 friends.

If some math genius out there can answer this I will be ecstatic!!!

See how many times 130 goes into 500,000,000

None the person that is asking you to be a friend, it is that persons choice to make you Mutual or a friend,
being are you a regular friend or someone that only see's you once in a while but still knows you. Facebook is such a wishie-washie thing to get involved in.
