What is the VBA userform code for prime factorization with listbox?

Answer 1

To create a VBA userform for prime factorization using a ListBox, you can use the following code snippet. First, set up a userform with a TextBox for input (named txtNumber), a Button (named btnFactorize), and a ListBox (named lstFactors). Then, use this code in the button's click event:

Private Sub btnFactorize_Click()
    Dim num As Long, i As Long
    lstFactors.Clear
    num = CLng(txtNumber.Text)
    For i = 2 To num
        While num Mod i = 0
            lstFactors.AddItem i
            num = num / i
        Wend
    Next i
End Sub

This code takes the number from the TextBox, factors it, and displays the prime factors in the ListBox.
