Excel: Formula for return a "1" if certain numbers are found

Hi guys I am using Excel 2011. I am trying to make a formula that will return a 1 if certain numbers like 26, 52, 35 etc up to 20 different ones are found in Column Ac1 down to Ac500. If no numbers are found then it just says 0. I tried this formula but it does not do multiples IF(ISNA(VLOOKUP(26,$AC$5:$AC$15,0,FALSE)),"1","0") I am thinking now that this formula is not the way to go. thoughts?
