A “First and Last Number” (FLN) is a number that is divisible by both its first and its last digits.
Using the nine non zero digits, I have written down a three digit and three two digit FLNs that, in this order, make a 9 digit FLN.
When the first and last digits of this FLN are removed I then obtain a seven digit FLN.
What is the 9 digit number?
