The smallest number is 1 and the largest number is 8. The range is the largest minus the smallest, so it is 8-1=7.
The greatest common factor of 8 and 12 is 4.
The largest 8-digit number is 9,999,999.
If you want to create the largest number you must use the highest number first, then the second highest and so on. Here we can use the three highest (8, 7 & 6) and the 4 because it has to be in the hundreds place. So the answer is 8476. If however you are allowed to use the digits more than once, it would be 8,488
4 is less than 8, so 4 over 8 is a proper fraction, which will not make a mixed number. You can simplify 4 over 8 to 1/2, though.
the answer would depend on what you are talking about. The largest number of those is 8. Or if you want to make the largest number it would be 84310
Using those 4 digits 6451 is the largest odd number you can make.
The largest 4 digit number in base 8 is 77778 (= 409510).
9,820 is the largest you can make.
The answer depends on what you are permitted to do in order to "make". The largest number that you can make by simply rearranging the three digits is 984. However, (4^8)^9 is of the order 10^43. You could get even larger numbers using factorials.
The smallest number is 1 and the largest number is 8. The range is the largest minus the smallest, so it is 8-1=7.
87,542 is.
Arrange them in descending order.
The greatest common factor of 8 and 12 is 4.
