A prime number can be less than 20, but it is not a requirement that the number has to be under 20 to be considered prime. Here is a list of all the prime numbers under 20: 2, 3, 5, 7, 11, 13, 17, and 19 .
The smallest prime number in which all of the digits are also prime is 2.The smallest multi-digit prime number in which all of the digits are also prime is 23.
It is always 1 and the prime number itself.
The number 1 and the prime number itself.
No, all prime numbers are deficient.

no, not all prime numbers are closed under addition. why? because, when you add 2 prime numbers you will not always get a prime number. example: 5+3= 8 5 and 3 are prime numbers but their sum is 8 which is a composite number..
The smallest prime number in which all of the digits are also prime is 2.The smallest multi-digit prime number in which all of the digits are also prime is 23.
It is always 1 and the prime number itself.
So we eliminate prime numbers. Note that the number 1 is neither prime nor composite. We have left:4689101214151618202122242526272830323334353638394042444546484950515254555657586062636465666869707274757677788081828485868788909192939495969899100
47 is already a prime number.
No, all prime numbers are deficient.
A prime number is one that is only divisible by 1 and itself. Just work out if it divides into anything. To do this try dividing the number by all prime numbers under its half way value.
The prime numbers under 16 are 2,3,5,7,11 & 13.
The number 1 and the prime number itself.
Ur mu m Isn't this great? She's had sooooo many children, they are all her factors
You cannot list all the potential prime factors. Any prime number can be a prime factor. There are an infinite number of prime numbers, so there are an infinite number of potential prime factors. If given a specific number, the prime factors for it can be listed.
