I used the ratio test and got zero as the final answer. So, this means that the given factorial series is convergent. Just for a follow-up question, is it true then that all factorial series are convergent?

How can I find out if 1/n! is divergent or convergent? I cannot solve it using integral test because the expression contains a factorial. I also tried solving it using Divergence test. The limit of 1/n! as n approaches infinity is zero. So it follows that no information can be obtained using...
