in VB Net i am trying to find the Prime factorization of a inputted number "n"

ex) 4 = 2 x 2, 16 = 2 x 2 x 2 x 2.

The code works for 4 = 2 x 2, but when i input 16 it gives me : 2 x 4 x 2 (4 is not prime, should be 2 x 2 )

32 gives me : (2 x 4 x 2 x 2 ).

How could i fix this ? Thank you for your help

Public class Form1 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.click Dim n As Long Dim i As Long Dim count As Long n = TextBox1.Text Do Until n = 1 For i = 2 To n If n Mod i = @ Then n = n / i TextBox2.Text += i & "" count += 1 TextBox3. Text = count End If Next i Loop End Sub
