Prime numbers are numbers whose only divisors are one and
itself. For example, 31 is a prime number because its only divisors are 1
and 31. However, 12 is not a prime number because it can be divided by 1,
2, 3, 4, 6, or 12.
There are NO PRIME NUMBERS among those 9digit numbers that can be formed by
rearranging the digits in the number:
Any number whose digits sum up to a number divisible by 3 is
divisible by 3. The above number has this property, and therefore any
number formed by
rearranging the digits of this number is divisible by 3 and therefore not a
prime number.
