Probably better ways to do it.

Spoiler: 

BEGIN
DECLARE @i FLOAT --Counter
DECLARE @t FLOAT --Three
DECLARE @f FLOAT --Five
SET @i = 1

WHILE @i <= 100
BEGIN
SET @t = @i /3
SET @f = @i /5
IF CHARINDEX('.',@t) = 0 and CHARINDEX('.', @f) = 0 
BEGIN
PRINT CAST(@i AS VARCHAR) + ' is a multiple of 3 and 5'
END
ELSE IF CHARPRINT('.',@t) = 0
BEGIN
PRINT CAST(@i AS VARCHAR) + ' is a multiple of 3'
END
ELSE IF CHARINDEX('.',@f) = 0
BEGIN
PRINT CAST(@i AS VARCHAR) + ' is a multiple of 5'
END
SET @i = @i + 1
END
END
