How is 115 composite?

Answer 1

Any number that can only be divided equally by itself and 1 is a Prime number.

115 is a composite number because it can be divided by 1, 5, 23, and 115.

Make your own program to check if a number is PRIME or COMPOSITE.

Cut and Paste the script code below into a Notepad,

then select "File > Save As..." to save the program

(somewhere handy like your desktop).

Save with a "File name" : Prime_or_Composite.vbs

and a "Save as type" : All files (*.*)

aNumber = InputBox("Please enter a number to check if it " & vbCrLf & _

"is a PRIME or COMPOSITE number:" ,"Enter a number", 0 )

If IsNumeric(aNumber) Then

Else

MsgBox "The value you entered " & """" & aNumber & """" & " is not supported."

WScript.Quit(0)

If IsNumeric(aNumber) Then

dim Result

Result = "PRIME"

For Counter = 2 to aNumber-1

If FormatNumber(aNumber/Counter,0)-(aNumber/Counter) = 0 Then

MsgBox aNumber & " can be divided equally by " & Counter

Result = "COMPOSITE"

Next

MsgBox aNumber & " is a " & Result & " number."
