Why is it that any 3 digit number that ends in 0 or 2 or 4 or 5 or 6 or 8 cannot be prime?
A prime number is evenly divisible only by itself and one. Any three digit number ending in 0, 2, 4, 6, or 8 is evenly divisible by 2 - so not a prime Any three digit number ending in 5 is divisible by 5, so not a prime number. The only even prime number is 2. The only prime number that ends in 5 is 5.

What number that is not divisible by 9 has one digit that is prime another digit that is a square and another that is not prime or square?
If one digit is a prime number, that digit must be 2, 3, 5, or 7. If one digit is a square, that digit must be 1, 4, or 9. If one digit is neither a prime number or a square, that digit must be 0, 6, or 8. So, 248 is a possible number. Another possibility is 436. There are other possibilities, as well.

Prime number using 4 1 and 0?
A three digit number ending with 4 and 0 is obviously divisible by 2, so that leaves only 1 for the last digit. The first digit can't be 0 (that would leave us with "41" - well, that one is prime in any case), so the remaining option is 401. That one is a prime number.
Why is it that any 3 digit number that ends in 0 or 2 or 4 or 5 or 6 or 8 cannot be prime?
A prime number is evenly divisible only by itself and one. Any three digit number ending in 0, 2, 4, 6, or 8 is evenly divisible by 2 - so not a prime Any three digit number ending in 5 is divisible by 5, so not a prime number. The only even prime number is 2. The only prime number that ends in 5 is 5.

What is the product of the largest single-digit prime number and the largest two-digit prime numbers?
