The number of six digit numbers that you can make from ten different digits ifrepetitions of same digit on the six digit number is allowed is 1 000 000 numbers(including number 000 000).If no repetitions of the the same digit are allowed then you have:10P6 = 10!/(10-6)! = 151 200 different six digit numbers(six digit permutations form 10 different digits).
27 three digit numbers from the digits 3, 5, 7 including repetitions.
There are 52.
1,000 of them. The list of possibilities will look exactly like the counting numbers from 000 to 999 .

3, which can be divided by the odd numbers 1 and 3.
Assuming all 45 digits are different (which they will not be if they are ordinary integers), then 456, if repetitions are allowed. That is 8303765625. If repetitions are not allowed then the number falls to 45*44*43*42*41*40 = 5864443200
