There are two systems of writing co-ordinates:
Degrees, Minutes, and Decimal Minutes
Degrees, Minutes and Seconds.
Your 764 is the decimal minutes part of the co-ordinate, and means 0.764 of a minute eg whole co-ordinate is 50 degrees, 39.764 minutes.
Since there are 60 seconds in a minutes, 0.764 minutes = (0.764*60) 45.84 seconds, so to the neares second, the co-ordinat is 50degrees, 39 minutes, 46 seconds.
Basically multiply the last part of the co-ordinat by 60 to convert decimal degrees into seconds.
Having said that, we enter decimal degrees into our Lowrance.....
