My Grandpa's Box #1

Question

My grandpa died last month. At the reading of his will, he left me a strange wooden box. A post-it-note on the side read "You were always good at puzzles." There was a number lock on the front that needed four numbers. On the side of the box there was an inscription reading:

$X10$

and numbers on the bottom that said:

$$101000.101101100000, -1001001.11101001010110101100,101000.10111001010001110100, -1001001.11110000100000101010, 110011.1100101110100011010, -0.(0)11000001011000101$$

I can't make heads or tails of any of it! Can someone help me find what the four numbers I need are?

EDIT - Hey so, something strange happened... I actually read the numbers wrong and the whole second line needed updated numbers. They have been updated so adjust your answers accordingly. Also, the website I used for co-ordinates was Google Maps, so use that to find the locations.

Hint:

This puzzle was inspired by Iconic Places and 820.5: Grandpa's silly math

Hint 2:

So I was playing around with the box and a drawer opened up! Inside there was a parchment saying:

1. Simple Math
2. Literally
3. Postcode

But, a guy, you should have already solved it by now.

EDIT - So noone seems to be getting the right location for the first coordinates, so I though I'd just say the location.

Answer 1

Partial:

The coordinates I got:
1) 40.2912, -73.955820 => Sea/C/6
2) 40.758900, -73.985130 => Times Square
3) 51.417050, -0.099013 => Bus Station in London (77)

Using the hint and something that I was thinking before but not quite the right way:

The equation we need to do is something like:
6 * (Times) sqrt (Square) (77) * (X) 10

so

6 * sqrt(77) * 10 = 494
This should be 4 digits not 3 so im guessing the 6 in the first picture is wrong (?)

Old Notes:

Some things I noticed and wild ideas I had in mind:

• Find numbers in each image:
  1) 6 - in title
  2) 1555 - address OR 29 in ad
  3) 77 - address or X68 - bus line

• the X68 in bus could be hex encoded for 'h', could have some connection to X10

• The letters NJ appear in both the first and third pictures

• Time Square could literally mean that we need to take the square root of the time of the first picture (20171112 / 8:56 Nov 12, 2017)

• there is meaning when combining the places of the images: sea, times square (Broadway), bus stop

Answer 2

Partial... These look like

Geographical coordinates converted to binary.

No idea what to do with the "X10" yet...

Answer 3

Partial (updated):

I got different results from @jafe

40.2912, -73.955820 which leads to a point in the sea off Long Beach, New Jersey, NJ6. There is a picture from the location by Nadia Romano.

40.758900, -73.985130 which is on Times Square, N.Y.
51.417050, -0.099013 which is 77 Beluah Hill, London

X10 means either times 10 (multiplication) or it has to do with a cross hair as if "here is the location".
Still I can't find what's common or joining the 3 locations and how to derive from them the missing code.
