Factor 10r–4.

To factor the expression \(10r - 4\), we can look for a common factor in both terms.

The common factor of \(10r\) and \(-4\) is \(2\).

Now, we can factor it out:

\[ 10r - 4 = 2(5r - 2) \]

So, the expression \(10r - 4\) can be written as the product \(2(5r - 2)\). The whole number greater than 1 here is \(2\).
