adjusting an if, then function in excel

[jack172]

Hi,
Basically I need a formula that says, if cell A1 is equal to either 1, 4, or 7, put a 1 in this cell, otherwise put a zero.

How can I do this?
I appreciate any help you can offer!

=IF(OR(A1=1,A1=4,A1=7),1,"")
or
=IF(ISERROR(MATCH(A1,{1,4,7},0)),"",1)
