Mathematics "riddle" help?

[Lena T]

Make a total of 657 using the following numbers:

50, 7, 6, 3, 8, 10

You may use the four operations, addition, subtraction, multiplication and division, but may only use each number once.
(The answer should be an equation)

Thanks!!

50 x 10 + 6 x 8 x 3 + 7 = 651.

Its the closest I could get.

Congratz 2 whoever got it!
