​

Answer 1

Step-by-step explanation:

Prime numbers can be divided by 1 and only itself, whereas composite numbers have factors other than 1 and itself. The given expression has 17, 11and 7 as its factors. ∴ it is a composite factor.

Answer 2

Answer:

Numbers are of two types – composite and prime. Prime numbers can be divided by 1 and only itself, whereas composite numbers have factors other than 1 and itself.

It can be observed that

(17×11×2) + (17×11×5) = 17{(11×2) + (11×5)}

= 17×{11×{(2) + (5)}} = 17×11×7

The given expression has 17, 11and 7 as its factors.

∴ it is a composite factor.
