Indeed, the number 16 has 5 factors, 1, 2, 4, 8, and 16.
16
Well, If we looked at this way: (224) = 16777216, so this number has exactly 24 factors. (324) = 282429536481, so this number has exactly 24 factors. (510)(210)(34) = 810000000000, so this number has exactly 24 factors.
Take any 5 prime numbers and multiply them together.
the number 105 does - 1, 3, 5, 7, 15, 21, 35, 105
16 and 81 have 5 factors
625 has five factors.
The numbers between 10 and 30 that have exactly 5 factors are 16 and 25. The number 16 has factors 1, 2, 4, 8, and 16. The number 25 has factors 1, 5, 25, but since it is a perfect square, it also includes the repeated factor of 5. These are the only two numbers between 10 and 30 that have exactly 5 factors.
Indeed, the number 16 has 5 factors, 1, 2, 4, 8, and 16.

A prime number has exactly two factors.
A number with exactly five factors is a number that is a prime number raised to the fourth power (p4). The factors are 1, p, p2, p3, and p4. Examples: The 5 factors of 24 = 16 are 1, 2, 4, 8, and 16. The 5 factors of 34 = 81 are 1, 3, 9, 27, and 81. The 5 factors of 54 = 625 are 1, 5, 25, 125, and 625.
Any number with five factors is composite. There isn't one in that range.
