Explanation:
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.
