Question

How many divisors of 1405 will have at least one zero at it's end?​

Answer 1

How many divisors of 1405 will have at least one zero at it's end?

Answer 2

$\begin{gathered}{\underline{\underline{\maltese{\Huge{\textsf{\textbf{\purple{Solution:}}}}}}}}\end{gathered}$

2^4 x 5^4 has (4 + 1)(4 + 1) = 25 divisors, 10^5 has 25 divisors that have at least one zero at its end.

So, 25 divisors of 1405 will have at least one zero at its end.
