No. For example, 61 is a prime number; 16 is not a prime number.

An emirp number is a prime number which, when you reverse the digits, produces a different prime number. Therefore, there are no single-digit emirp numbers. The first three emirp numbers are: 13, 17, 31

None. If it is a multiple of another number, in this case 4, it is not a prime number.
