### BARS::End 504 at AZ Hwy-260 Evaluates to 'phi'

This road sign was found at the junction of Forest Road 504 and AZ Hwy-260, one mile west of Heber, Arizona.

The sign says...

```   +----------------------+
| <- Heber        1    |
| <- State Hwy. 260 -> |
|    Payson      52 -> |
+----------------------+
| 504 |
| end |
+-----+

the numbers are:  1  260  52  504

the math is:

(504 + 1)    505
---------- = --- = 1.61858974
(260 + 52)   312

the golden ratio = 1.61803399
```

Our result (`1.618`) is 'phi' truncated to the thousandths

```   [exercises]

1) evaluate  lcm(260, 504)
2) evaluate  gcf(260, 504)
3) approximate  sqrt(52)
4) no or yes. 1 is a prime number
```
##### BAB Content Prior to BARS Analysis

The top portion of the road sign approximates a rectangle.

The "504 End" portion looks like a square made out of two equally sized rectangles.

Beyond the sign I think there is a diamond-shaped sign warning us about an upcoming octagon-shaped stop sign.

[computing] `504 (gateway timeout)` is not `404 (object not found)`.
