4 and 9
These numbers between 1 and 40 have an odd number of factors: 4, 9, 16, 25, 36.

The factors of a number cannot be greater than the number itself. So there are no factors of 4 between 30 and 50.
one of them is 4 because it has 1, 2 and 4 as factors
The factors of 16 are 1, 2, 4, 8, and 16.
4 and 9
These numbers between 1 and 40 have an odd number of factors: 4, 9, 16, 25, 36.
Six has four factors and is in between the twin primes 5 and 7.
The factors of 16 are: 1, 2, 4, 8, and 16.
Answer: The factors of the number '4' are 1, 2, and 4.
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.

3 x 4 = 12
16, with factors 1, 2, 4, 8 and 16.
