Question

How will you show that (17 × 11 × 2) + (17 × 11 × 5) is a composite number?

Answer 1

Hey there!

A number which has more than 2 factors is called a composite number .

We know that, For every number, One and itself are factors. To prove that a number is composite, you need to prove that it has a third factor other than itself and one.


So , Given

(17 × 11 × 2) + (17 × 11 × 5)

= 17 ( 11 * 2 + 11 * 5 )

= 17 ( 11 ( 2 + 5 ))

= 17 * 11 * 7

So, We see that given number (17 × 11 × 2) + (17 × 11 × 5) has 17 , 11 , 7 as its factors other than one and itself.

Hence, It is a composite number.

Therefore, (17 × 11 × 2) + (17 × 11 × 5) is a composite number.
