16 factors.
The number of factors of a number is calculated as the product of the powers of the number written in power format increased by 1. As there are required to be 5 factors, and as 5 is a prime, it can only be achieved if the number has a prime factorisation which is a single prime raised to the 4th power. The smallest prime is 2, and 2⁴ = 16 The next prime is 3, and 3⁴ = 81 which is too big. → the required number is 16 (which has the 5 factors 1, 2, 4, 8, 16).
16 has an odd number of factors; its factors are 1, 2, 4, 8, and 16
Factors of 16 are: 1 2 4 8 and 16 Factors of 15 are: 1 3 5 and 15
