Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits.
There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundred’s place respectively.
So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120
Similarly, the total no.of ways by which 4 digits numbers can be formed = 6.5.4.3 = 360.
the total no. of ways by which 5 digits numbers can be formed = 6.5.4.3.2 = 720.
The total no.of ways by which 4 digits numbers can be formed = 6.5.4.3.2.1 = 720.
So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.

279,999,720
What kind of numbers are decimals with a repeating pattern of digits?
either irrational numbers, integers, integers, rational numbers, or whole numbers
How many numbers are there between 100000 and 125000 where the digits are in order from least to greatest?
Only one. 123456.
What is first smallest six digit number?
100000 of course. If digits have to be different then 123456.
How many 6 digit numbers which consist of all the digits 123456 are divisible by all of 123456?
None. Extremely simple proof: To be divisible by 5 the units digit must be 5. But then it would not be divisible by 2.

How many six digit numbers can be formed using the digits 0123456789 Example equals 123456 or 098765?
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).
How many numbers are between 100000 and 125000 where the digits are in order from least to greatest no digit can be repeated?
There is only one number and that is 123456.
How many numbers between 10 an 30 have digits that have a sum of 5?
