I knew once, but I forgot. Is it something like 1.44? It's been refered to as God's number. Can't remember, but by continiously deviding one number of the Fibbonacci sequence into the next one (or the other way around) you would get closer and closer to this number the more you do it. Does anyone know what I'm talking about? Don't tell me it's pi, because that's not what I'm talking about.

In mathematics, a perfect number is defined as an integer which is the sum of its proper positive divisors, that is, the sum of the positive divisors not including the number. Equivalently, a perfect number is a number that is half the sum of all of its positive divisors, or σ(n) = 2 n.
Six (6) is the first perfect number, because 1, 2 and 3 are its proper positive divisors and 1 + 2 + 3 = 6. The next perfect number is 28 = 1 + 2 + 4 + 7 + 14. The next perfect numbers are 496 and 8128.
These first four perfect numbers were the only ones known to the ancient Greeks.

The ratio that you approach with successive divisions of the Fibonacci sequence is (1 + square root(5))/2, which is often called PHI, the "golden ratio". It is a shade over 1.6180.. It is nonsense to talk about "God's Number" because He is creator of all! Maybe you are thinking of 144 which is both a square AND a Fibonacci number. Mathematicians refer to "perfect numbers" as those which are the sum of all their divisors (NOT prime factors): 6 is the smallest (not counting the trivial case of 1): 6 = 1 + 2 + 3. The next is 28 = 1 + 2 + 4 + 7 + 14. They get large in a hurry: the eighth perfect number is 2305843008139952128. There is no limit to the number of perfect numbers.

Most are confusing the Golden ratio which is a very interesting number with what Perfect Numbers actually are: the first 8 perfect numbers are below. For more see Euclid or Mathworld on the web

A simple spreadsheet cal gave me 1.618033989 when I divide the greater Fibbonacci number with the smaller and 0.618033989
when I do the other way. So the difference is 1.0000000, but the decimals are the same.
Now decide which is your God's number.

Phi the golden ratio. it is not really a number but a proportion. it is related to the angles and relations in the sides of a pentagon star It is approximated in the Fibonacci sequence becoming more accurate a the series progresses. It is related to the spiral growth patterns of plants, shell fish, people and almost all life.. your heart is built enclosing the spiral based on this ratio

6! It's a perfect number mathematically (all its factors add up to itself (except the number itself)) 1 + 2 + 3 = 6. Though it's more the Devil's number, I suppose... 666.

I think is PHI or as mentioned the golden ratio and it's 1.61803.... Everything in life is supposed to come back to this number. How true this is I do not know!

1.618........ See Robert's answer, he's more accurate than me. This is the number linked to virtually everything on earth. Our high school maths teacher told us that it's the basis of even the most complicated patterns of nature!
