It is already a four-digit number.
It depends. If the numbers are only used once then it is 24. More precisely it is 4!. (4 factorial which is 4x3x2x1). The same would apply to any number of digits assuming they are used once each. If there is replacement involved (any number used any number of times like 7777 or 6688), then the answer would be 256. Or in other words, the number of possible numbers raised to the power of how many digit positions there are (44). So if the question was how many 5 digit numbers can you make from 1234567?75=16807
1000
951999
Every 9-digit combination of those numbers is a multiple of 3. None of them will be prime.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 4950, exactly as in the question.
The smallest four digit number is 1000. It is even so 1001 is the smallest four digit number that is odd.
9876 is the largest four digit number you can make if all the digits must be different.
1050 is the four digit number don't know which mathematical procedure to use it took me 5 mins to make a small C# program and ta-da! that's it. :)) cheers
this question doesnt make sense
-7510 is the smallest.
use the digit 8 four time to make 89
9
61 is prime. You cannot make 61 by multiplying four digits.
what is the largest 4-digit number you can make
10 000 if you can start with zero.
.0123
how make the answer im don/now
