What does "no digit may be composite" mean, that all the digits have to be prime numbers?
If so, then 9 is composite, and 8 is composite, but 7 is prime, so the (trivial) answer is 777777. Any other number meeting the criteria given is smaller.
This is so glaringly obvious that I can't help thinking you meant something else. You might want to ask again, but be more specific next time.

Is 45005 a prime or composite number?
"Composite" means that the number has smaller factors; "prime" means that it doesn't. Look at the last digit. If the digit is 0, 2, 4, 6, or 8, the number is divisible by 2. If the last digit is 0 or 5, the number is divisible by 5. If it none of those, the number may still have additional factors; but checking for this last digit can often quickly give you an answer.
