The smallest number with 16 factors is determined by considering the prime factorization of the number. Since the number of factors is related to the exponents of the prime factors, we need to find a number with a prime factorization that allows for 16 factors. To achieve this, we can start with the prime factorization of 2^3 * 3^2, which results in (3+1)(2+1) = 12 factors. To reach 16 factors, we can multiply this by another Prime number raised to the power of 1, resulting in 2^3 * 3^2 * 5^1 = 360.

240 is the smallest number with at least 19 factors. 240 has twenty factors: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240 262144 is the smallest number with EXACTLY 19 factors
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
240 is the smallest number with twenty factors.
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).
16 has five factors.

the answer would seem to be ten.
240 is the smallest number with at least 19 factors. 240 has twenty factors: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240 262144 is the smallest number with EXACTLY 19 factors
64 (1, 2, 4, 8, 16, 32, 64)
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
240 is the smallest number with twenty factors.

The smallest number that has exactly eight factors is 24. The factors of 1,2,3,4,6,8,12, and 24
Every number has factors. They are endless.
16 if the prime factors don't have to be distinct. 210 if they do.
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).
