Explanation:

Step1: Find first missing factor

We know that \(1\times x = 20\), so \(x=\frac{20}{1}=20\).

Step2: Find other factor pairs

Factor pairs of 20: \(2\times10 = 20\) and \(4\times5=20\) (or \(5\times4 = 20\), \(10\times2=20\) but we can use positive integer pairs).

Answer:

First row: \(1\times\boldsymbol{20}\)
Second row: \(\boldsymbol{2}\times\boldsymbol{10}\) (or \(\boldsymbol{10}\times\boldsymbol{2}\))
Third row: \(\boldsymbol{4}\times\boldsymbol{5}\) (or \(\boldsymbol{5}\times\boldsymbol{4}\))
