Question

(i) begin{tabular}{c|c}
5 & 3825
hline 5 & 765
hline 3 & 153
hline 3 & 51
hline & 17
end{tabular}
We have ( 3825=3^{2} times 5^{2} times 17 )
(ii) We use the division method as shown below:
begin{tabular}{r|r}
17 & 7429
hline 19 & 437
hline 23 & 23
hline & 1
end{tabular}
[
therefore 7429=17 times 19 times 23
]
