Six: 234, 243, 324, 342, 423, and 432.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
To form a 5-digit number using the digits 1, 2, 6, 7, and 9 without repetition, we can use all five digits. The number of different arrangements of these 5 digits is calculated by finding the factorial of the number of digits, which is 5!. Therefore, the total number of 5-digit numbers that can be formed is 5! = 120.
874321 is the largest number made from all these digits.
To determine how many digit numbers can be formed using the digits 2, 3, 5, 7, and 8, we need to consider the number of digits in the numbers we are forming. For a 1-digit number, we can use any of the 5 digits. For a 2-digit number, we can choose 2 out of the 5 digits and arrange them, giving us (5 \times 4) combinations. We can continue this for 3-digit, 4-digit, and 5-digit numbers, which will yield (5), (20), (60), and (120) respectively. Therefore, the total number of digit numbers is (5 + 20 + 60 + 120 = 205).
To form a 7-digit number using the digits 1, 2, 3, 4, and 8, we can use any of the five digits for each of the seven positions. Since repetition of digits is allowed, the total number of 7-digit numbers is calculated as (5^7). Thus, (5^7 = 78125). Therefore, there are 78,125 possible 7-digit numbers.

012345 or -543210, if negative numbers are permitted.
874321 is the largest number made from all these digits.
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).
24680 using only even numbers or 12346 which is an even number
9,999,876 is the greatest seven-digit number using four different digits.
100122 or, if negative numbers are permitted, -998877
No, a 10-digit phone number that is missing the last three digits can not be a legitimate number. In order for a number to work, it must have 3 numbers for an area code and seven digits for the phone number itself. Some telemarketers are now using fake numbers to hide from the people they're calling.
