Web7 jul. 2024 · The number of divisors function, denoted by τ(n), is the sum of all positive divisors of n. τ(8) = 4. We can also express τ(n) as τ(n) = ∑d ∣ n1. We can also prove that τ(n) is a multiplicative function. The number of divisors function τ(n) is multiplicative. By Theorem 36, with f(n) = 1, τ(n) is multiplicative. Web$\begingroup$ For example, 12=2^2*3 has 6 divisors. To make more divisors, we could multiply by 2,3, or 5. This will take us to 24, with 8 divisors, 36 with 9, or 60 with 12. So …
