If $G=langle{a_i}_{i=1}^rrangle$ is nilpotent with $|a_i|=m_i$, show that $|G|$ divides a power of...
$begingroup$
use this notation for the following $textbf{Theorem}$ -
$textbf{notation}-$ $G^n$ is the subgroup generated by $n$th power of elements of $G$
$textbf{Theorem}$- In a finitely generated nilpotent group, $cap{G^p}$, for any infinite set of primes, is finite,(follows by a paper of HIGMAN) does it help me to prove this question above. I don't think so.
Is it true, that a group generated by finite elements of finite order is finite. If it is true then to prove $G$ is finite in the problem is easy, and don not require nilpotency. But it should not be true, but what can be an example?

so we need nilpotency to say $G$ is finite. How can i approach this problem?

Use induction on the nilpotence class, and consider the central quotient in the non-abelian case.

I can't use induction, until I show $G$ is finite

@BhaskarVashishth The induction is on nilpotence class, which is finite by assumption.
