Files having permission as 777 and not accessed since last 7 days.
$ find . -perm 777 -atime +7
$ find . -perm 777 -mtime +7
$ find . -perm 777 -ctime +7
Output: Will return all the files which are having permission as 777 and not accessed/modified/changed more than 7 days.
Note: We can change the values of -perm & -atime/mtime/ctime to achieve the required.

Files having permission as 777 and of size greater/less than 10 MB.
$ find . -perm 777 -size +10M
$ find . -perm 777 -size -10M
Output: Will return all the files which are having permission as 777 and of size greater/less than 10 MB.

Files having permission 777, less than 10MB and have not accessed more than 7 days.
$ find . -perm 777 -size -10M -atime +7

Conclusion:
As explained above we can use the find command switches (-perm/-atime/-mtime/-ctime/-size and so on.) to perform complex searches in single line. Practice will take you to the heights so keep practicing and enjoy the FIND...!!!!
