If you consider 1 and the Prime number itself as factors then: 2
If you do not consider 1 and the prime number as factors then: 0
A prime number is one that does not have any factors apart from 1 and itself.
You factor the number into prime factors, dividing each prime out.
43 is a prime number because it has exactly two factors, 1 and 43. 33 and 63 each have 3 as a factor as well as 1 and themselves, so they are composite numbers.
Just two: 1 and the number itself.
4096 is the smallest number with exactly 13 factors. (Including 1 and itself as factors).192 is the smallest number with exactly 13 properfactors, (excluding the number itself).120 is the smallest number with at least 13 factors (it has 16 factors)To find the smallest number with exactly N factors (for example, N=12):Factor N into primes, (for example, 12= 2*2*3Subtract 1 from each of the prime factors (for example, 1,1,2)Sort them by largest first (for example, 2,1,1)Raise successive prime numbers to these powers (for example, 2^2,3^1,5^1)Multiply these together (for example: 4*3*5 = 60; 60 is the smallest number with exactly 12 factors).
Distinct prime factors are the prime factors that are distinct (or different) from each other. A list of distinct prime factors is a list of one of each different prime number that is a factor. For example, the prime factors of 8 are 2, 2, and 2. The only distinct prime factor is 2, which occurs multiple times.

Prime numbers
Each of the 25 prime numbers from 1 to 100 has exactly two factors, 1 and the number itself. The other 75 numbers from 1 to 100 are not prime numbers because none of them have exactly two factors.
You factor the number into prime factors, dividing each prime out.
Prime numbers have as factors the number 1 and their own number. Example: 37 is a prime number because its only factors are "1" and "37". If the prime number had further factors, it would no longer be prime.
No. For example, 30 has the factors 1, 2, 3, 5, 6, 10, 15, 30; while 31 only has the factors 1 and 31 - in other words, it's a prime number. Note that there are arbitrarily large prime numbers (there is no last prime number); each of them has exactly two factors.
Each digit is a prime number that has only two factors which are itself and one The prime factors of the number 22 are 2 and 11
Each prime number has 2 factors: 1 and itself.
43 is a prime number because it has exactly two factors, 1 and 43. 33 and 63 each have 3 as a factor as well as 1 and themselves, so they are composite numbers.
Just two: 1 and the number itself.
If the numbers are prime numbers, the prime factor of each number is the number itself. If the numbers are not prime numbers, the prime factors of each number are each of the prime numbers by which the number in question can be divided without a remainder.
