Show that the number \(5 \times 17 \times 17 + 3 \times 17\) is a composite number.
 
Solution:
 
Given \(5 \times 17 \times 17 + 3 \times 17\) 
 
\(=\) \(\times\) \((5 \times 17 + 3)\)
 
\(=\) \(\times\)
 
Factors of second term are  i,i,i,i,i,i,i,i
 
So, it has more than factors.
 
Thus, the given number is a composite number.
 
[NOTE: Give the factors in ascending order]
