For 52, the answer is: No, 52 is not a prime number. The list of all positive divisors (i.e., the list of all integers that divide 52) is as follows: 1, 2, 4, 13, 26, 52. For 52 to be a prime number, it would have been required that 52 has only two divisors, i.e., itself and 1.

So, 1 can't be a prime number because it has only one factor (1 is itself), 0 can't be prime since it has no factors at all, 2 has two factors (1 and 2) so it is prime, and is in fact the smallest prime.

Is 22 a prime number? For 22, the answer is: No, 22 is not a prime number. The list of all positive divisors (i.e., the list of all integers that divide 22) is as follows: 1, 2, 11, 22. For 22 to be a prime number, it would have been required that 22 has only two divisors, i.e., itself and 1.

1 is not a prime number as it only has one factor - itself. 2 is the only even prime number. Every other even number has 2 as a factor, and so will not be prime. There are an infinite number of prime numbers.

The first 25 prime numbers (all the prime numbers less than 100) are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 (sequence A000040 in the OEIS). . Therefore, every prime number other than 2 is an odd number, and is called an odd prime.

A prime number has exactly two factors, 1 and itself. For example, 13 is a prime number because the only factors of 13 are 1 and 13. The number 8 is not prime because it has four factors: 1, 2, 4 and 8. The number 1 is not a prime number because it only has one factor (itself).
