The first digit can be 1, 2, or 3,
to make it a 4-digit number, and
to make the fourth digit 9 or less.
first= first digit
fourth=3%2Afirst= fourth digit
third= third digit
second= second digit =third

system%28second=third%2Cthird%2Bfourth=3%2Asecond%29 ---> third%2Bfourth=3%2Athird ---> fourth=2%2Athird

system%28fourth=3%2Afirst%2Cfourth=2%2Athird%29 ---> fourth is a multiple of 2 and a multiple of 3 ---> fourth=6

system%28fourth=3%2Afirst%2Cfourth=6%29 ---> first=2

system%28fourth=2%2Athird%2Cfourth=6%29 ---> third=3

system%28second=third%2Cthird=3%29 ---> second=3

The number is highlight%282336%29 .
