Answer 4

you need to find

smallest 3 digit number that has a 6 digit number when multiplied by itself is 317 and 317x317= 100489

now you need to find a largest 3 digit number that when squared still gives you a 6 digit number

that is 999, and squared is 998001

so all the combination between 317 and 999 when multiplied result in a 6 digit number between 100489 and 998001

so there are 998001 - 100489= 897512 6digit numbers which are product of two 3 digit number
