7532.
To find all prime numbers less than ten, we have {2, 3, 5, 7}.
Now, let's arrange these prime numbers in descending order:
First, we write down the largest prime number less than ten, which is 7.
Next, we write down the next smallest prime number, which is 5.
Then, we write down 3, followed by 2, the smallest prime number less than ten.
Combining these digits, we get the number 7532.
Therefore, the number formed by arranging all prime numbers less than ten in descending order is 7532.
