What are the factors of 1/2 x

Depending on the value of 'x', the numerical value of that expression

could have almost anything for factors.

For example, if [ x=512 ] then 1/2x = 256, and the factors of 1/2x are

1, 2, 4, 8, 16, 32, 64, 128, and 256.

But the only factors you can always be sure of, that don't depend on the

value of 'x', are

1, 1/2, x, and 1/2x.
