Brace yourselves for the ultimate number challenge!
I have a ten digit number, abcdefghij. Each of the digits is different, and
- a is divisible by 1
- ab is divisible by 2
- abc is divisible by 3
- abcd is divisible by 4
- abcde is divisible by 5
- abcdef is divisible by 6
- abcdefg is divisible by 7
- abcdefgh is divisible by 8
- abcdefghi is divisible by 9
- abcdefghij is divisible by 10
What’s my number?
[To clarify: a, b, c, d, e, f, g, h, i, and j are all single digits. Each digit from 0 to 9 is represented by exactly one letter. The number abcdefghij is a ten-digit number whose first digit is a, second digit is b, and so on. It does not mean that you multiply a x b x c x…]
This is super challenging and will take lots of time but I am confident that somebody in Ospreys’ class can crack this! 🙂
Why don’t you pair up or form a team to work on it?
