The amount of time resources (number of atomic operations or machine steps) required to solve a problem expressed in terms of input size. If your question concerns algorithm analysis, use the [runtime-analysis] tag instead. If your question concerns whether or not a computation will *ever* finish, use the [computability] tag instead. Time-complexity is perhaps the most important sub-topic of complexity theory.

Sieve of Eratosthenes for factorization: bitwise complexity?
As is well-known (and easy to prove), carrying out a sieve of Eratosthenes on the first $N$ integers takes a number of word operations in the order of $N \sum_{p\leq \sqrt{N}} 1/p \sim N \log \log N$, …
