printing the max of each field

hi guys im very new to scripting and i have a problem. i need to use awk in my script and the script needs to print the max for each of the columns in a file. for example:

58 25 30 15 10
38 10 38 8 9

./max numbers.txt

yes its a homework problem i have wrestled with using the following script in some kind of for loop but everytime i do it just goes out of control and throws errors about the syntax.
BEGIN { max1=0
}
$1>max1 { max1=$1
}
END {print max1}
i was thinking that maybe if i can put it in a for loop and make it repeat this action as many times as there are fields but i have not had any success thank you again
