Question 60875: Recently a very wealthy individual died and left a large amount of money to be distributed to two individuals. The problem was that this person did not tell anybody who these two people were. This rather cryptic message was left to help someone solve the mystery.
Social security numbers have nine digits. Assuming there is a unique social security number for each person, find the number that contains no 0's and the first number from the left is divisible by 1, the first two numbers from the left are divisible by 2, the first three numbers from the left are divisble by three and so on. No number is used twice. What is the number??
