6 possible 3 digit combonations
You can select 9 numbers for the first digit, 8 numbers for the second digit, and 7numbers for the third digit; so 504 (e.g. 9*8*7) different three digit numbers can be written using the digits 1 through 9.
The sum is 22 times the sum of the three digits.
There are 900 three-digit numbers.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.

5 x 10 x 5 = 250 different numbers, assuming there is no limit to each digits' use.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
27 three digit numbers from the digits 3, 5, 7 including repetitions.
757
24 three digit numbers if repetition of digits is not allowed. 4P3 = 24.If repetition of digits is allowed then we have:For 3 repetitions, 4 three digit numbers.For 2 repetitions, 36 three digit numbers.So we have a total of 64 three digit numbers if repetition of digits is allowed.
