3x(x - 5)(x + 5)

25

You can just try that out. If it's only one prime factor to the third power, it means the number is either 23, 33, 53, 73, 113 etc.. if you check those, 53 is 125. 113 is already 1331. 73 is 343 and therefore fits the description, so the number you're looking for is 343.

23*3 = 29 = 512

3x^3(x - 4)

The only common factor of those two terms is the number three, giving you: 3(x3 - 8y3)

3x(x - 5)(x + 5)

x(x + 1)(x - 1)

a3x2 - 216x2 factors to x2(a - 6)(a2 + 6a + 36)

-8

simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34

In case you meant 64x^3 - 27y^3, that factors to (4x - 3y)(16x^2 + 12xy + 9y^2)

Yes.
