Show that the number \(5 \times 19 \times 17 + 3 \times 19\) is a composite number.
Solution:
Given \(5 \times 19 \times 17 + 3 \times 19\)
\(=\) \(\times\) \((5 \times 17 + 3)\)
\(=\) \(\times\)
Factors of second term are
So, it has more than factors.
Thus, the given number is a composite number.
[NOTE: Give the factors in ascending order]
