The number '1' as it has only one factor(1 itself).
It is not a Prime number as a prime number is a number which has exactly two factors--one is that number itself and the other is 1, examples of prime numbers are:
5(factors 1&5 only),
7(factors 1&7 only),
13(factors 1&13 only)
and so on...
Any number which has more than two factors is called a composite number. Examples are:
6(factors 1,2,3&6),
8(factors 1,2,4&8),
12(factors 1,2,3,4,6,12)
and so on...
A lot of numbers do. These are called prime number.s The prime numbers under 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 and 97. These aren't the onliy prime numbers, though. There are many others greater than 100.
Answer: 0 and 1. No other products have factors that are the same as the product or 'have 1 factor'.
Proofs:
0 * 0 = 0 Note: 0/0=undefined (see notes below)
1 * 1 = 1
Notes:
Some people may argue that 0 is not a factor of the product 0 because 0/0=undefined. You can decide for yourself (the factor 0 * the factor 0 does in fact = the product 0. As your question specifically asks about [which] numbers have 1 factor, this answer does in fact properly answer your question regardless of this (0/0=undefined) fact.
Any prime number has only two factors which are itself and one.
All the Prime Numbers have only 1 Prime factor which is itself.
All numbers have a common factor, even if it's only 1. Numbers whose greatest common factor is 1 are said to be relatively prime or co-prime.
Since every number is a factor of itself, that would have to be zero.
